when i turn on my car in a cold start, the rpm bogs down when i step on it, it feel like some sort of misfire, and this only happens on a cold start, ones it warms up the car runs normal, also for when i hold the rpm at 1500 to 1600 it does this......


what could all this be? please help..

 

first of all cel. pull that.and if you did put in an aftermarket steering wheel please get rid of srs light.

check iacv clean it out completely seam foam works great if its dirty.
the fitv might need adjustment.
but most likely when the idle is like that bouncing real quick its a vaccum leak

 

ok will do that today, thanks man.

 

ok, i cleaned the iacv and im still having the same issue. i also notice that when i unplug the iacv theres no reaction to the motor whatsoever, so im assuming is no good, it is also bypassed, there is one small hose tied up on both tips.
