noticed my 82 idles high, is it supposed to? ehat rpm is it suposded to idle at? ou people are so good on replying to questions we have. Thanks so much for helping! Arlene
Arlene,
Carb. cars usually Idle around 650 - 700 or there abouts after the idle sets, cold it is somewhat higher between 900 - 950. I don't know the specs for the 82 CrossFire Injection system. I'm sure someone else here does, and will reply too.
I looked for the idle speed set-up in the Haynes Manual. From 1981 on they say to refer to the vehicle emmissions sticker. You should find this located on the underside of the hood.
Hi Arlene,
The computer on your car controls idle speed. It should be around 650 - 700 rpm. If you have a fast idle, you have a vacuum leak or a bad idle speed motor. Your car is a crossfire motor isn't it?

Your idle speed should be 450 in park with the iac holes plugged. (minimum air). The ECM determines the dile speed with the IAC's functioning. It could be anywhere from 650-900, depending on what accessories are turned on.
A good indication of too high idle is when the rear slams down when you shift into gear. If this happens idle is too high. Also, don't trust the tach, use a scanner to read the idle speed that the ECM registers. This is a much better indication of the actual speed and if something's wrong.
