My car idles at 800-1200 rpm and my buddys stays at 1500 . Is there a problem with my car or his car.

Any CEL? Typically, if the idle is sporatic like that, it usually means there's a vacuum leak around the throttle body and the I.A.C. (bigger black thing on the tb) is trying to compensate and stabilize the idle, or the I.A.C. itself could be bad. According to the factory service manual, engine idle should be 850 +/- 200 rpm's.

so for the most part im good. i rarely stay at 1000 rpms or above . Look s like my buddy is fucked. All those abbreviations i dont get. Im farely new to the board and the talon engine. So if you could please explaing what the tb . i.a.c and all those are that would be great.

TB = throttle body - you know where this is, right?
IAC - Idle Air Controller, this is on the TB, back side and lower with a connector on it. :thumbsup

Your is right around target idle. Your friends sounds like he could have a vacuum leak, or various sensors going bad.

Mine idles between 800 and 1200 as well, found out it was the TPS, Throttle Position Sensor.

I appreciate the explaining of the iac and tb . On any other board they would say something stupid. So thanks for not being dicks.

and i dont know where the tb is .

Facing the engine it toward the back. Follow the intake pipe (stock is black plastic). The intake clamps to a metal part, that's the TB.

TB = Throttle Body, which is a plate that opens an dcloses reghulating the amount or air the engine can take in. It opens and closes as you get on and off the gas pedal.
