IDLE AIR CONTROL VALVE

what would be the signs of it going bad or what are the effects if it is bad,my car car is out of safe mode yet i cant get past 5k rpms and alot of people are saying that this might be why,??

umm well for me, the check engine light kicked on and I noticed idle rpms were tons loer and led to it being easier to stall... but then I cleaned it out and it was all good.
I doubt that's the solution to your problem because the name "idle" in IACV suggests that it only messes with your idle... but I could be wrong.

signs of bad iacv


Idle RPM too high
Idle fluctuating wildly
Idle RPM too low and/or erratic
Idle fluctuating when loads occur to the engine
Fast idle too low for cold starts

ok so ill give it a good clean, but this wouldnt be causing the problem right?

but this wouldnt be causing the problem right?

to the op:

is this a chipped ecu w/ a launch control at 5k? if so and you don't have a cel the speed sensor is bad, but it still communicates diagnostic voltage to the ecu without communicating any speed voltage. that'll cause it to not throw a cel, but will also tell the ecu that you are standing still even though you are rolling=hitting the launch limiter.
