idle problem
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?

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.

idle problem
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
