i have a freshly rebuilt quad 4. it idles rather high...1100 rpm about, even when its warm. also when i let off the gas it takes a bit for the rpms to drop. the code for a bad idle came up. suggestions on where to start?

what was the code?? sounds like IAC sensor..
idle air control.
my race car is the same way till it warms up a little..

the scanner read code 35... i think... its been a couple weeks since i last scanned it. any ways i got a code for the ac... which i had disconected, and for what it called "bad idle"... thats all it said..nothing else.
i'll check out the iac sensor tho
thanks

Try the TPS too. I had idle problems that ended up being that.

im pretty sure its the iac sensor, b/c i completly forgot to install it. do you guys know if its a two wire or a one wire? im just wondering b/c if it is a two, then mayb i can pull one off of a 3.1 or sumthin.

ok if im not mistaken the iac goes on the throttle body, and is a 4 wire. the sensor im missing is the one that goes on the air filter housing itself. is that a one wire? also what is its actual name... im guessin its something like air intake sensor.
thanks for you help

AIT (air intake temp) sensor I believe. It is one wire on my 3.1.

Hi Guys, New to the board but I thought this would be the best place to look, a few days ago I noticed a little problem with my Idle, I have a 1988 GT with a 2.8l, when I am at idle for a wile I notice my tech (I have a digi dash) slowlly drop under 700 then it shuts off. Then it wont start again untill the car cools down or I give it a little gas to keep the RPM's above 800, Now the car drives fine at this point but if I let off the gas at say a light it shuts off and I have to repeat the process, looking under the hood I found a sensor not connected hanging off the rear exaust maniford, the wire to the sencor is purple. I can't for he life of me find where it connects to but I feel these two are related, Searched mt haynes manual but its usless. Thanks again for your imput
