Well I tried cleaning my IAC, no luck, still have terrible idle and humming noise. Called the stealer and they have a Motorcraft IAC in stock for $181. Thats alot of cash, does anyone know of a place I can get a Motorcraft alittle cheaper???
Thanks.

Good find on Amazon - that's cheaper than Rock Auto.

Have you cleaned your MAF? Oiled air filters can foul them.

 

I got mine from Rockoholic online (Rock Auto Ebay site) for 50 something.

 

Thanks alot.
Just ordered online from rockauto.
it cost me $96 shipped to my house, about half of what the stealer wanted. Just hope it fixes my problem.
Thanks again

I have autozone IAC's in both my 5.4's(39.99) Been running them in the truck for 3+ years and the van for 2 no issues.

 

just installed my Motorcraft IAC from rockauto.......truck working GREAT!!! Finally.
Thanks for all the help!!!

 

Just had to buy one for my mustang. It has the 2 valve 4.6 and I paid $75 for one at o'reillys.

 

Same here.. changed it in the parking lot in about 10 minutes. Worked like a charm and waaayyy cheaper than the dealer. Holy crap! They sure are proud of them!

 

Thats where I got mine for my truck. Same price. Works great.

 

would an IAC cause 171 and 174 ses codes? I have tried everything that I can think of and keep getting those codes!!

 

Mine didn't throw any codes. How is you truck idling? A bad IAC symptom is usually a high idle,lower then normal idle,stalling or a fluctuating idle so if your truck is idleing fine then most likely your problem is something else.
