Last week i took my throttle body off to clean it up. Took off all the sensors and got it nice and clean. After i put everything back together the idle was very low and would stumble and stall when taking off from a start. So replaced the IAC and it got a little better. But now on a cold start the idle jumps from all around. Uasally from 1000-2000 rpms. After it warms up it gets better. Still stumbles a little and stalls everyonce in a while. Do you think its another bad IAC. Ive disconnected the battery to let it relearn but its been almost a 100 miles since then. Any help would be good.

 

if the rpm surging problem started with the new IAC, then i'd say its bad. i'd recommend a mopar brand or SMP brand name only.
