Im new to DF but read alout of great stuff on here so here it goes im on my 3rd iac in 3 months the only thing i have not checked yet was the wires from iac to pcm anyone else have this problem??? Or a solution ??

 

welcome to df.
what is your problem? no idle or surging idle or other?

i had a cold start surging idle problem. after replacing 3 iac's, i replaced the TPS and it fixed my problem.

also make sure you are not breaking the iac. don't twist, turn, pull, or push on the pintle. also don't operate it plugged into the harness and not installed. i tried that. bad move.

 

Truck is shutting off when i let off the throttle at around 800 rpm i replace tps reset pcm an still no change im taking the TB off today and givng a good clean but i just had it off 8 months ago an cleaned it when i replace the plenum gasket

 

Check the wiring from PCM to IAC. make sure no wires are screwed up, and the connections are clean, and tight.

Cleaning the TB REALLY WELL is a good plan.

Go with a different brand IAC......

 

+1 ... What brand have you been using ? And you are disconnecting the negative battery cable before removing and installing new one right? Do that when you clean the TB as well.

 

Yes i disconnect the battery before and ive been using BWD iac from advance auto parts

 

I'm having the same problem. Sometimes it shuts off when I come up to a stop sign and the idle starts dropping, then at 0 it'll shut off.

I've been told it's my IAC too.

 

I changed my IAC 3 times before I realized my battery was causing me all my grief. If your battery isn't providing the sensors with the proper voltage it will do some wacky things. I would check your battery.

 

Ok guys pulled TB off an cleaned it really well checked all wires for IAC, TPS and MAP why i was at it they all checked out good put it all back together and it running great for now thanks for all the help!!!
