Well its been a while, my car is starting to idle shitty again, and when warm it just cranks and cranks and finally starts up I am really starting to think its the iac cause i cleaned the maf and i cleaned the iac and its still doing it... No check engine light is the weird think if it was the maf it would def trip a light, It has a really choppy idle like it can't decide where is normal it smells rich and when i shift normally ours cars have that bwahhhh sound when you let off to shift mine just cuts back all at once and pops sometimes through the exhaust its really weird and i just don't know what to do, oh and i also checked for injector and vacuum leaks and their isn't any......:mad:
 
if you do try replacing the IAC, I always hear that you need to pony up the few extra dollars and buy it new from ford instead of refurbished from the part stores.

Yeah i would rather spend the extra 50 bucks for quality and not get the autozone cheapy and have to replace it again......

If it's running rich have you looked elsewhere????? O2 sensors? Plugs?
Plugs were replaced at 22,000 miles, and o2's (upstream) were replaced at 25,000 when i added the new x pipe... It only has 38,000 on it now. If the 02's were not reading correcting wouldn't it throw a code???? There is absolutely no miss under acceleration it is only at idle, or when trying to start after sitting for a few minutes, it used to clear up after it idled for a few, but now it idles shitty constantly! I need to install a wideband!!!!!
