car stalling

[88iroc]

my 88 iroc has been stalling out lately. After i drive it for a couple min its fine, but when i start it up in the morning or after its been sitting for a while it'l just stall out after a couple seconds of running. I also notice that it stalls out sometimes when i switch it into reverse. do u guys hav ne idea wats wrong wit it.

i would start with cleaning the IAC. it screws into the throttle body and has a 4 wire connector

manual or automatic???

but i also agree that it sounds like the IAC or.. the ICM. My IROC was doing the same thing, i spent easily a week chasing my tail trying to figure out what the problem was, finally narrowed it down to one of three things, the ICM was one of em, swapped it with the ICM from my RS, and the problem went away. its cheap, less than 50 bucks and easy to do. i would reccomend doing that first.

IAC is the Idle Air Control Valve, its located in the throttle body, its a hex head 1-1/4in across, with a four pin electrical connector sticking out of it.

ICM is Ignition Control Module, it is a small electronic control module located under the rotor of the distributor. to get to it, take the distributor cap off, and undo the two screws holding the module in place, it will have three electrical connectors plugged into it, youll have to take them off. put the new one in, after using some di-electric grease on the metal contact, screw it down, plug it in, and put the distributor back together, and start the car up.
