I popped a p0505 code the other night giving me a IAC malfunction and after reading the other posts you guys said try cleaning the IAC b4 replacing. I just got upset taking the stupid thing off, so i went out and bought a new one. Now my truck wont idle at all. I can get it to run just by holding the throttle, but if i let go or pop it in gear, she stalls. I have no clue as to what to do. I took off my TBS because there seems to be a concensus that they are junk and noticed i have a bad fit on my CAI. i have a slight gap on the back side but i dont think that would throw a code. does anybody have any suggestions?

i always come along and disagree with squirrel on the IAC adjustment/calibration thing. according to everything i read, no calibration is necessary, although it is a good idea to reset the pcm when installing a new one.

try resetting pcm. if that doesn't work, and you new iac is plugged in properly, then you probably got a bad one. its very common, especially with the crappy ones from autozone and advance. take it back and tell em its no good and swap it for another. i once went through 4 or 5 to get one that worked right.

edit - i think its a waste of time to clean the stupid thing.

 

And I always agree to disagree with Vaughan, but he buys cheap IACs

 

only the cheapest for me.

 

i went through and tore off my whole throttle body area and cleaned it, checked all the voltages going to the IAC, and guess what? Vaughan was right! my cheap IAC from advanced(only store open on sundays) was bad! replavced it, reset it and no prob so far. thx
