1989 Acura Integra LS
Car

1989 Acura Integra LS

This is a 1989 Acura Integra LS, a small car from the late ’80s that can be had with a manual transmission. The caller says it feels jerky when you’re creeping slowly, like pulling out of a parking lot or backing up.

Term

five-speed

“Five-speed” means the car has a manual transmission with five forward gears. The problem described happens when you’re using the lowest gears while moving very slowly.

Term

horsepower to weight ratio

It’s a simple way to compare how strong the engine is versus how heavy the car is. More power for the same weight usually means quicker acceleration. Less power or more weight usually means it feels slower.

Term

ignition timing

Ignition timing is when the spark happens inside the engine. If it’s too early or too late, the engine can run poorly or act weird. Checking it is a common step when troubleshooting engine problems.

Volvo V70 cross country
Car

Volvo V70 cross country

This is a Volvo wagon called the V70, and “Cross Country” is the tougher, higher-clearance version. It’s meant to handle rougher roads and weather better than the regular wagon.

1988 Volkswagen Golf
Car

1988 Volkswagen Golf

This is a Volkswagen Golf from 1988. The Golf is a popular compact car, and the caller is saying they have one from that year.

Term

fuel filter

A fuel filter is like a screen for your gas. It helps keep junk out of the fuel system so the engine can run smoothly. If it’s clogged, the car may hesitate or run rough.

Term

fuel injectors

Fuel injectors are the parts that spray gas into the engine. If they get gummed up from old fuel, the spray can come out wrong, and the engine may run rough or not burn the fuel well.

Term

atomize

To atomize fuel means to break liquid fuel into a fine mist so it can mix with air and burn efficiently. If the injectors aren’t atomizing well (often due to clogging), some fuel may not vaporize and won’t burn completely.

Term

fuel vaporized

Fuel has to turn into vapor to burn efficiently in the engine. If it comes out as a dribble instead of a mist, it may not vaporize, so the engine can’t burn it properly.

Term

floor it

“Floor it” means you press the gas pedal all the way down. The engine responds by demanding more fuel and pressure, which can sometimes make a clogged injector spray better.

Term

spray pattern

The spray pattern is how the fuel comes out of the injector—like whether it’s a fine mist or uneven. If it’s wrong, the engine may not get the right mix of fuel and air.

Brand

Tecron

Techron is a fuel additive—basically a cleaner you put in with your gas. The idea is that it can help remove gunk that may be clogging or dirtying fuel injectors.

Company

Chevron

Chevron is the company behind Techron, a cleaner you add to your fuel. In this discussion, it’s brought up as a way to improve injector cleanliness.

Term

add-ins

“Add-ins” here means products you pour into your gas to help clean the fuel system. People use them when they suspect deposits are causing problems.

Term

sensors

Sensors are the car’s little monitors that tell the engine computer what’s going on. If one is wrong or not reading correctly, the computer can make bad adjustments and the car can act like there’s a fuel problem.

Term

out of range

“Out of range” means a sensor reading is outside what the car expects. If the computer gets a bad reading, it can adjust the engine incorrectly and cause drivability issues.

Term

winterized

“Winterized” means getting the car ready for cold weather. For most cars, that usually involves the coolant system so it doesn’t freeze in winter.

Term

flushed the radiator

Flushing the radiator means draining and replacing the coolant. If air gets trapped in the system, it can make gurgling noises and cause weird behavior until it’s corrected.

Term

heater coil repair

The heater coil is what helps the car’s heater make warm air. If it’s “broken,” coolant may not flow correctly through it, so the heat system can act up or leak.

Term

air trapped

Sometimes air gets stuck in the car’s coolant lines instead of coolant filling everything. That air can block flow and make weird gurgling sounds when the system tries to circulate coolant.

Term

heater core

Your heater core is the part that warms the air inside the car. Hot coolant runs through it, and a fan blows air over it so you get heat in the cabin.

Term

coolant

Coolant is the fluid that keeps the engine from overheating. It also helps provide heat for the cabin through the heater core.

Term

bleed the system

Bleeding the system means getting the trapped air out of the coolant. You run the car and top up coolant until the bubbles stop, so heat and cooling work normally again.

Term

bleeding these

Bleeding means getting air out of the cooling system. Air can stop coolant from circulating well, so the heater may not work right until the air is removed.

Part

radiator cap

The radiator cap is the lid on the cooling system that helps it stay pressurized. If air gets trapped in the cooling system, changing the car’s angle can help push that air out so the system works correctly.

Concept

air out

“Get the air out” means removing trapped air from the cooling system. If air is trapped, the system can act like something is broken even when the main parts are fine.

Place

export PA

This is a place name—Export, Pennsylvania—mentioned because the caller is talking about a dealership there.

Honda Accord
Car

Honda Accord

The Accord is a regular family-style car that’s meant for daily driving. The podcast is talking about an older 1994 model that’s still running well. That’s notable because many people expect older cars to need more work.

Ford Contour
Car

Ford Contour

This is a Ford Contour, and the caller says it has a manual (stick-shift). They’re describing trouble shifting as the car gets faster, which usually points to something in the clutch or shift system rather than the engine itself.

Term

manual transmission

A manual transmission is the stick-shift setup where you choose gears yourself. You use the clutch to switch gears, so shifting problems—especially changing gears at speed—often point to the clutch or the linkage.

Term

downshift

A downshift means switching to a lower gear. Drivers do it to get more power, and if it becomes hard to downshift at higher speeds, something in the clutch or shifting system may not be working right.

Term

revving up the engine

Revving the engine means making the engine spin faster (higher RPM). When you’re trying to shift, the engine speed matters—if the RPM is too high or too low, the gears may not go in easily.

Term

front wheel drive

Front-wheel drive means the front wheels do the work of moving the car and turning it. If something in the front drivetrain is loose or worn, it can affect how the car behaves and even how the shifter feels.

Part

motor mount

A motor mount holds the engine in place. If it’s broken or loose, the engine can move around while you drive, which can mess with the parts that connect to the shifter and make gears harder to select.

Part

shifter

The shifter is what you move to choose gears. If the shifter mechanism or its connections are worn or out of adjustment, the transmission may not line up correctly, so you can’t get into gear unless you slow down or stop.

Term

torque

Torque is the engine’s twisting force. When you rev higher, the engine is trying harder to turn the drivetrain, which can make it tougher to slot the transmission into gear.

Term

RPM

RPM tells you how fast the engine is spinning. Telling someone to rev to a certain RPM is a way to test whether shifting gets worse when the engine is working harder.
