aftermarket parts

"That's a lot of aftermarket parts. For whatever reason there, whatever you're doing, Eric, you're."

Aftermarket parts are pieces you can buy from other companies to replace or improve the original parts that came with your car. They’re usually cheaper and can make your car run better or look cooler.

Coil packs are the parts that spark the fuel in your car’s engine. If they’re bad, the engine can misfire or run poorly.

Part

intake

"So instead of a focus, it's the 232 AMG 2003. And I was going to do the just do like coil packs and intake."

The intake is the part of your car that brings air into the engine. A good intake lets the engine breathe better, which can help it run smoother.

Part

heater case

"There was a couple different ones. They have one that's enclosed in the heater case."

The heater case is a metal box inside your car that keeps the heating parts safe and lets warm air go into the seats. Think of it like a small room for the heater’s motor and resistor.

Part

blower motor

"But if you can get to the bolts, the most likely failure on that thing is going to be the heater motor and the resistor."

The blower motor is the part that pushes air into your car’s vents. It uses electricity from the battery to move warm or cool air around.

Part

resistor

"The motor gets old and dirty and starts dragging, pulling a lot of amps, and that burns up that resistor."

The resistor is a small component that controls how much electricity the blower motor uses. If it gets too hot, it can fail and stop your heater from working.

Term

E85

"run E85 and that means they've tuned it and no matter what you do, if they've tuned this thing to run on E85"

E85 is a special kind of gas that has a lot of alcohol in it; cars that can use it run faster and are cleaner.

Term

rich condition

"you know, that high pressure on that on that side is that leaking and causing a rich condition."

Rich means the car is getting too much fuel compared to air, which can make it run poorly and waste gas.

Term

running rich

"it's running rich, obviously. Check your temp sensor."

If your car’s fuel mixture is too heavy, it means there’s more gasoline than air in the engine. That can waste gas and hurt performance.

Part

high pressure sensor

"looked up said that that, you know, that it could be the wiring going to that high pressure sensor and so I was like, thinking"

It’s a small device that tells the car’s computer how much air pressure is inside the engine, which helps keep performance smooth.

Part

wiring harnesses

"looked up said that that, you know, that it could be the wiring going to that high pressure sensor and so I was like, thinking"

Part

map sensor

"they should be but I'm like I thought I had it what I did the map sensor and you know I've done so many things on it"

The MAP sensor tells the car’s computer how much air is going into the engine so it can add the right amount of fuel. Think of it as a pressure gauge for the engine’s breathing.
