#2623: Virtual Dopeslaps
About this episode
A mix of listener calls and classic Car Talk problem-solving: a 92 Oldsmobile owner argues with a service manager about whether you must use the emergency brake daily—turns out handbrakes can help adjust rear brakes, but the “every day” rule is overstated. Another caller’s 1978 Land Cruiser backfires with flame-like exhaust; the brothers suspect intermittent ignition (igniter/ignition switch). A 1990 Chevy Lumina minivan stalls after short stops, likely due to hot-soak ignition components. Between calls, they debate coasting in neutral on a manual and run a Bedouin-themed towing puzzler.

oil change
"So I take it in for oil change and check up. I try to take care of it, right?"
An oil change is when the old engine oil is removed and replaced with new oil. It keeps the engine running smoothly and helps protect it from wear.
An oil change is routine maintenance where the engine oil is drained and replaced with fresh oil, often with a new oil filter. It helps lubricate engine parts and carry away heat and contaminants.
service manager
"So then this little manager mechanic. Manager mechanic. Like the service manager."
A service manager is the person in charge of the shop’s service work. If something goes wrong or a job wasn’t handled properly, they’re often the one who steps in.
A service manager is the person at a dealership or repair shop who oversees the service department, including scheduling, job assignments, and customer communication. In many shops, they’re the escalation point when a customer feels work wasn’t done correctly.
emergency brake
"do you use your emergency brake every day? ... You should use your emergency brake every day in order to keep your brakes up to factory specs."
Your emergency brake is the brake you use when the car is parked. It’s different from the brake pedal you use while driving, and it helps keep the car from rolling when you stop.
The emergency brake (often called the parking brake) is a separate braking system from the main brakes. It’s primarily meant to hold the car when parked, but some people also use it periodically to help keep the mechanism working properly.
keeps the pedal high
"[368.1s] and thus keeps the pedal high. [370.5s] Well, so if I'm backing up every once in a while, [372.8s] aren't I doing okay?"
“Pedal high” refers to brake pedal position/travel—when the rear drum brakes are properly adjusted, the pedal doesn’t need to travel as far. Poor adjustment can cause extra pedal travel and a “low” or mushy pedal feel.
adjust the brakes
"They could have simply adjusted the brakes, which is what you really asked them to do. But on a lot of cars that have this mechanism, you can adjust the brakes yourself..."
“Adjust the brakes” refers to setting the correct clearance between brake components so the brakes work properly and don’t drag. On some older or cable/lever parking-brake systems, the adjustment can be done by cycling the handbrake or using an adjustment mechanism.
backfires
"And it kind of hesitates and then it backfires. And the problem is when it backfires, it's like a tank going off."
A backfire is when your car makes a loud pop or bang, sometimes with flames. It usually means fuel is igniting in the wrong place, like in the exhaust, often when you change throttle.
A “backfire” is when unburned fuel ignites in the exhaust or intake system, causing a loud bang and sometimes flames. It often happens during throttle changes—like lifting off the gas or sudden acceleration—when combustion timing and fuel/air mixture aren’t behaving as intended.
flames
"It shoots flames, which is kind of alarming to my neighbors and people walking down the street and so forth."
Flames from the exhaust mean extra fuel is burning outside the engine. It’s usually a sign something is off with how the car is running.
Flames coming from the exhaust are a sign that fuel is igniting in the exhaust stream rather than being fully burned in the cylinders. This is more than just a noise issue—it can indicate improper combustion control, often tied to ignition/fueling or emissions system changes.
tailpipe
"The result would be the biggest explosion and ball of fire coming out of your tailpipe, because what would happen is while you would, had the key off, the pistons were still going up and down and sucking gasoline into the cylinders."
The tailpipe is where exhaust comes out. If you see flames there, it usually means fuel is burning in the exhaust instead of in the engine.
The tailpipe is the exhaust outlet where gases leave the vehicle. Flames there indicate combustion is occurring in the exhaust stream rather than only inside the cylinders.
ignition system
"And it may be then that you have a fault with your ignition system. Even, even a bad switch could cause this, but I would think it would be more likely would be intermittent spark."
The ignition system is the part of the car that makes the spark to start combustion in the engine. If it’s not working right, the engine can misfire and feel like it’s running rough.
The ignition system is what creates the spark that ignites the air-fuel mixture in the engine’s cylinders. If it’s faulty, you can get misfires—where some cylinders don’t fire correctly—leading to rough running and hesitation.
Subaru Boxer engine
"and an available 260-horsepower turbocharged Subaru Boxer engine for confident performance wherever the trail may lead."
A “Boxer” engine is Subaru’s flat-style engine. The pistons move left and right, and the design can help the car feel balanced and stable.
A Subaru Boxer engine places cylinders opposite each other in a flat layout, with pistons moving horizontally. This design can help with low center of gravity and smooth operation, though it’s also a distinctive Subaru engineering choice.
turbocharged
"plus standard symmetrical all-wheel drive and an available 260-horsepower turbocharged Subaru Boxer engine"
A turbocharger is like a power booster. It squeezes more air into the engine so it can make more power, especially when you need it.
Turbocharging uses exhaust gases to spin a turbine that compresses incoming air. More air (and fuel) can be burned in the engine, typically increasing power and efficiency versus a non-turbo engine of similar size.
X-Mode
"Standard X-Mode with hail descent control offers greater ability to optimize traction in almost any condition."
X-Mode is Subaru’s off-road mode. It helps the car manage traction so you can drive more confidently on slippery or rough ground.
X-Mode is Subaru’s driver-assist/off-road traction system that adjusts throttle response, transmission behavior, and traction control to improve grip. It’s intended to make it easier to move confidently on loose or uneven surfaces.
traction
"offers greater ability to optimize traction in almost any condition. Discover the all-new Outback at Subaru.com slash Outback."
Traction is how much grip the tires have on the road. If traction is low (like on snow or loose dirt), the car can spin or slide unless systems help manage it.
Traction is the grip between tires and the road surface, which determines how well the vehicle can accelerate, brake, and corner. Many off-road modes work by managing traction control and power delivery to prevent wheel spin.
brakes had failed
"Well, the way it could possibly be, the only scenario I can envision is that Fred's brakes had failed. So if, in fact, Frank had tried to tow him home, he'd be crashing into him every time he stopped."
“Brakes had failed” means the car couldn’t slow down or stop. If the towed car can’t brake, it may keep rolling and hit the car in front when that car stops.
Brake failure means the vehicle can’t slow down or stop as intended. In a towing scenario, if the towed car’s brakes don’t work, it can surge forward and collide with the towing vehicle when the tow car slows.
brake lights
"On the other hand, if Fred is driving the broken car in the front, and Frank steps on the brake, and he steps on, no, and he steps on the brake, the brother will see the brake lights..."
Brake lights are the red lights that turn on when you press the brake pedal. They tell the car behind you that you’re slowing down, so they can react too.
Brake lights are the red lights that illuminate when a driver applies the brakes. In the scenario described, the idea is that seeing brake lights helps the following driver react and slow down.
1990 Chevy Lumina APV
"Well, I have a 1990 Chevy Lumina APV minivan. It's 136,000 miles on it."
This is a Chevrolet minivan from 1990. Sarah uses it to drive clients around for her job, so it’s the main car being discussed. The “APV” is just the specific minivan version name Chevrolet used.
The Chevrolet Lumina APV is an early-1990s minivan platform from GM (Chevrolet). In this episode, it’s the specific vehicle Sarah uses for her realtor work, so it frames the real-world reliability and wear-and-tear context. The “APV” is the model line name used by Chevrolet for this minivan.
136,000 miles
"Well, I have a 1990 Chevy Lumina APV minivan. It's 136,000 miles on it."
“Miles” here is the odometer reading, a key indicator of how much wear a vehicle has accumulated. For older cars used for frequent short trips—like shuttling clients to showings—mileage plus driving pattern can matter as much as age. Listeners often use mileage to gauge expected maintenance needs and risk of failures.
leaving the car running
"Have you considered leaving the car running? Exactly what I was thinking. I mean, that's the one way to solve that problem. Just leave the thing running."
Sometimes people leave the car running so it doesn’t have to restart. That can hide a problem, but it doesn’t actually solve what’s wrong with the car.
Leaving a car running during a stop can mask symptoms that only appear after heat soak or after a restart attempt. However, it’s a workaround, not a fix—problems like ignition/fuel faults can still worsen, and idling can create other risks (fuel dilution, overheating, or battery/charging issues depending on the car).
Chevette
"I was disturbed, but I would rather have been driving a chvette."
A Chevette is an older, more basic Chevrolet. The joke is that the speaker would prefer a plain, no-frills car over a fancy one used to impress people.
“Chevette” refers to the Chevrolet Chevette, a compact car that’s often remembered as practical and inexpensive rather than luxurious. The contrast here is emotional: the speaker would rather be driving something humble and straightforward than a luxury car used mainly for appearances.
battery was dead
"He came in to use it the next morning, and the battery was dead. He had left his running lights on."
A dead battery means there wasn’t enough power to start the boat. In this case, the lights were left on and drained the battery.
A dead battery means the battery voltage dropped too low to power the starter and ignition systems. In this story, the cause is an electrical load (running lights) left on while the boat sat overnight.
running lights
"He came in to use it the next morning, and the battery was dead. He had left his running lights on."
Running lights are the lights that help other people see the boat. If you leave them on too long, they can drain the battery.
Running lights are the boat’s navigation/visibility lights that stay on while the boat is in use or at rest. Leaving them on overnight can drain the battery enough that the engine won’t start.
starter spins up
"The starter spins up. You can hear the motor turn, but it doesn't engage the flywheel... Again, it spins up, but doesn't engage the flywheel."
When the starter “spins up,” it means it’s getting power and trying to crank. If it still won’t start, the starter may not be grabbing the engine correctly.
“Spins up” describes the starter motor running at speed, usually because it’s receiving power. However, if it spins up without engaging the flywheel, the problem is typically mechanical (starter drive/solenoid/gear engagement) rather than electrical power delivery.
diagnostic process (bench test vs installed behavior)
"So they pull the starter off... they put it on the bench in the shop... It jumped right up... So they put it back in the boat. Again, it spins up, but doesn't engage the flywheel."
They’re using a smart troubleshooting method: test the part by itself, then put it back and see if the problem returns. If it only fails when installed, the issue is often how the parts meet up, not just the part alone.
The episode describes a classic troubleshooting pattern: test the suspected part off the vehicle (bench test), then reinstall and verify the symptom. When the starter works on the bench but fails when installed, it narrows the cause to engagement mechanics, alignment, or the interface between starter and engine.
window fogging (condensation)
"But now that we're living in New York, the windows are fogging. And my husband tells me the reason the windows are fogging is because I'm breathing too hard in the back seat."
When the inside air is warm and humid and the windows are cooler, moisture turns into tiny droplets and makes the glass look foggy. It’s basically the same thing as fogging up a bathroom mirror.
Fogging windows usually happens when warm, moist air inside the cabin contacts cooler glass and condenses into tiny water droplets. In cars, it’s often influenced by cabin humidity, temperature differences, and whether the HVAC system is clearing the glass.
heat on seat
"I'm so huddled down in the coat in the back because he has no heat on seat. But these guys sweat when they think hard."
Heated seats warm the person sitting in the seat. They don’t necessarily clear the windows, so you can still get fogging if the front HVAC isn’t helping.
“Heat on seat” refers to heated seats, which warm the occupant directly using built-in heating elements. Heated seats don’t replace windshield defrost/ventilation, so a car can have seat heat but still fog if the HVAC airflow to the glass isn’t working.
vents
"But he has turned off the vents in the front. So you're only getting the heat in the back."
Vents are the openings where the car blows heated or cooled air. If you shut off the front vents, the windshield may not get enough warm air to stay clear.
“Vents” are the outlets where HVAC air is directed (front defrost, dashboard vents, rear outlets, etc.). Turning off the front vents can prevent warm, dry air from reaching the windshield, increasing the chance of fogging.
condenses immediately
"You don't have a six-degree windshield in Kansas. When that windshield is cold, anything that hits it, any moisture that hits it, condenses immediately."
When the windshield is really cold, the moisture in the air turns into tiny droplets right away. That’s what causes fog.
When the windshield is very cold, water vapor in the air turns into liquid droplets quickly—this is condensation. That’s why defogging is more difficult in colder climates: the glass cools the air fast enough for moisture to form.
gasoline
"But remember that they're practically giving the gasoline away. Even in these days of high gasoline prices, the stuff should cost $10 a gallon."
They’re talking about how much gas costs. When gas is expensive, it changes how people think about driving and what cars they buy.
The discussion is about the price of gasoline per gallon and how that affects driving costs. Fuel price is a major factor in how often people drive and what kinds of vehicles they choose.
$10 a gallon
"Even in these days of high gasoline prices, the stuff should cost $10 a gallon. And they're selling it for a buck and a half."
They’re using a price per gallon to show how expensive gas can get. It’s just a way to compare costs.
This is a reference to fuel pricing, using a per-gallon cost to illustrate how expensive gasoline can be. It helps frame the later comparison to a much lower pump price.
a buck and a half
"And they're selling it for a buck and a half. See what you started here, Robert?"
They mean gas is really cheap here—around $1.50 per gallon. The cheaper gas makes driving feel less painful.
This phrase refers to a very low gasoline price (about $1.50 per gallon in context). The point is that cheap fuel makes it easier to justify driving more or choosing less fuel-efficient vehicles.
fill up your tank
"If you were in Italy, it would be costing you 150 bucks to fill up your tank every time you went there."
They’re talking about buying enough gas to fill the tank. It’s used to compare how expensive it is to fuel up.
“Fill up your tank” refers to purchasing enough fuel to top off the vehicle’s fuel capacity. The transcript uses it to compare the cost of fueling in different places.
Cars.com
"Just head on over to the car talk section, the cars.com, and order it there in the car talk store."
Cars.com is a website where people shop for cars. Here, they’re just saying you can find the Car Talk show item through that site.
Cars.com is a major online marketplace for buying and selling vehicles. In this segment, it’s referenced as the place to order a Car Talk show product, tying the brand to the podcast’s “where to get it” instructions.
