Did you take it back and try a replacement one? But yes OEM is best for something like that.

Honestly the only real reason to go to any of the chain stores (IMO) is to get fluids or if its something really stupid like bolts or rags or cleaners. I'll wait the 2 or 3 days it takes Rockauto to ship me my parts that I look up/verify for a LOT cheaper and with a MUCH bigger selection. I still do have an Autozone rewards card though, 5 transactions of $20 or more and you get $20 store credit. This pretty much means every 5 oil changes I do get the oil/filter for free the next time.

Rockauto has an excellent selection of Motorcraft parts for reasonable prices.

I second this. I personally don't get any actual parts from autozone. I got an IAC from autozone and the car made a super loud trumpet-like noise. I switched it out for a NAPA IAC and it is perfect and still working

Napa isn't much better honestly. Prices are not that great and the last parts I got from them were Napa brand rotors with horrible runout issues. Only time I'll ever go to Napa is to grab a Wix filter and honestly I don't even do that anymore. Motorcraft filters are fine and are like $3 when I get my oil.

Well for me NAPA stuff has been just fine. Been getting my parts from them for a long time and haven't had any issues.

Plus It was hard for me to justify ~$90 on a motorcraft IAC when it's probably just going to go bad like it did in the first place.

Then again there's original IAC's that have been on the car it's entire life and in excess of 300k miles. Or a car that's had 5 of them in it's life. It's luck of the draw and some parts will fail sooner than others.

Yes that is very true, with these cars the electronic stuff like the valves and sensors it really is just luck of the draw.

My IAC had less than 50k on it when it went

Autozone told me they gave me the DURALAST brand and made the mistake of not selling me the HITACHI BRAND IAC that supposedly came with originally. So they don't carry them n they had to order it. Be here in a couple days. Is that the brand it comes with?

OEM Ford is what came with it originally. If they contracted it out Hitachi then maybe but if you buy one from Ford its a Motorcraft unit.

Hmmm. Rockauto's website says Hitachi are OEM parts. Hell, if I'd seen that, AND, didn't need the special "Bullitt" IAC made only by Motorcraft, I probably would give that one a shot.
It's half the price of the Motorcraft...

Yeah that's the one bad thing about a Bullitt, its a one off year special edition that has just enough different **** to be annoying. But they are cool as hell and they got the intake ALL 2V cars should have got IMO. I remember when you could still buy the Bullitt intake swap kit new for like $1300 in 2003. Same with the Bullitt suspension for $400 that same year.

Yep. I've been waiting on the 130 amp alternator to arrive that I ordered. Another Motorcraft only part.
With that part, though, I believe the Cobra owners share my pain as well.

Yeah the 4V has a different setup too. One thing I liked about my 95 Cobra, same everything as the GT as far as that sort of stuff. It literally is a GT with a FRPP HCI and 13" brakes. There are a ton of other small things but for the most part that is the difference. I miss that car, if I was in a state that didn't require a sniffer I might very well sell my modular and try to get into another 5.0 Cobra.

Duralast=Duracrap. Only thing duralast that is any sort of decent are the tools... sort of. Like I said I mostly use places like Autozone for fluids or cleaning stuffs etc... Anything else you are way better buying from Rockauto. Don't EVER use Duralast rotors... have fun with massive runout. Not to mention you can get Raybestos and Centric pieces off Rockauto for the same price and those are REALLY good rotors.

That is a good deal. If I am spending more than $40 I break up the purchase just to take advantage of that lol

They usually don't like that. However I drive right by every day so if I'm going to need $40-$60 worth of parts for the weekend I'll just get half one day and half the other.

Ended installing the hitachi brand one that they sell at autozone and so far it works perfect. Has 1 year warranty so we will see how good it is.

Would you suggest the same for a V6? I am going to replace mine when my next oil change is do and I looked on rockauto and I think a Motorcraft iac is a little more expensive than duralast. I don't mind paying a little extra if there is such a difference.

There were two OEM IAC valves used on the new-edge GTs. The early one (through '01-1/2 AFAIK) was made by Hitachi, the later one by Nippon-Denso. They are interchangeable as they both have the same mounting pattern and electrical characteristics.

Hitachi IAC (with vented solenoid):



Nippon-Denso (no solenoid vent):



The Duralast branded valves sold at Autozone are made (or more accurately I suspect distributed) by Wells Manufacturing, an OEM supplier. They are likely actually made by Hitachi, Nippon-Denso or one of the other Asian OEM parts suppliers. I ran one on my '03 GT for 5 years and 80k miles with no problems.

It is important to disconnect the battery for 5 to 7 minutes after changing any engine control device so as to clear the KAM (Keep Alive Memory) and force the PCM to relearn things like the idle air and fuel trims, etc. It is also the first thing I do when tracking down idle problems as the process by which the PCM adaptively learns these things works faster when the KAM is first cleared, and slows as the miles rack up.

Here is how to test the IAC...
