I have already adjusted and tested the TPS it is ok, ive already adjusted the minimum air intake, i just replaced the IAC and the damn thing still idles like crazy when cold.
It starts but then it will go down to about 500 rpm, bog and sound like its gonna die, then go up to 1500 rpm just before it dies, this happens for about 5 minutes until it finally stops. Someone please help me figure this out!!

Mark,

Have you looked into the CTS and MAT sensors? You can check them with an ohmmeter.

 

Thanks a ton I will look into those, by chance do you know where they are located? I have a stealth ram if that makes a difference.
