    Idle Air Control

    I had the up and down idle on my 04 Mustang so I ordered this and it did the trick. Delivery was very fast and the part was very easy to install. It took 15 minutes to install. It was the answer to my problem. It did not come with a new gasket so make sure you pick one up before putting it on.

    IAC

    do not buy an aftermarket iac, tried 2 of them and they had my car with a hanging idle around 21/2 to 3 rpms constantly. Bought a ford original motorcraft iac, put it on and problem solved. I highly recommend the ford iac from American muscle.

    Problem fixed!

    My 2002 GT was starting to make a sort of burping sound and I thought it could be the plugs, but talking to a mechanic friend, he told me to try changing the IAC valve. It took 5 minutes and solved the problem. As far as the quality of the product, you can't go wrong with oem parts on your Mustang.

    Quality product

    Randomly my stang started having idle issues, very rough surging. The rpm's would jump and drop from 1000 to 200 continuously as the car ran, under acceleration it was normal. Come to a stop and the issue would start again. Very common issue with 99-04 mustangs, cleaning the IAC hardly works and if it does it isn't permanent. It will happen again. Be careful when choosing a new IAC, the new edge body style came with two types. One has a black cylinder "spring loaded" I think, on top next to the motor, the other does not. Please pay attention to which one your car has, it is easy to mistake these parts. I would recommend this part as a solid replacement "OEM quality". It fixed my issue right away, reuse the old gasket or purchase a new one. Good luck.

    rough idle fix it!

    this is a great part to help out an aging mustang, if you have a rough idle, this is the most likely part to fix it. Price is a little steep but worth the peace of mind

    DO NOT BUY AN AFTERMARKET IAC!!

    I tried 3 different aftermarket IAC's and they did not work! Unless you like a 2,000 rpm idle. Do yourself and your Mustang a favor and get the genuine article from American Muscle. Simple 10 minute installation. Couldn't be easier.

    Excellent Part - FORD IAC Exactly as Described

    This IAC is an exact replacement for the stock part. My 02 mustang GT has 145,000 miles on it and it started making a funny sound, like when someone blows across the top of a water bottle. Almost like a fog horn. Only at idle. So I originally sprayed some carb cleaner into the IAC and the problem went away for a few weeks. But all the sudden, it came back and started to idle rough. Also, the idle would hang when i was rolling in neutral before coming to a complete stop. So i decided to get this Idle Air Controller replacement to see if it would fix the problem. It fit perfectly, got rid of the sound and the rough idle, and the idle doesn't hang anymore either. Perfect solution if you have any of these problems.

    IAC valve

    This is a direct fit Ford replacement part. Was somewhat surprised that the gasket wasn't included. That is why I gave a 4 star rating. Fit was perfect and valve does its job.

    Warning all '02 GT owners!!

    So after struggling with idling issues on my '02 gt, I figured out that the IAC valve had gone bad. So I bought a new one and replaced it, but for some reason it didn't fix the problem. I couldn't figure out why. The shops near by couldn't figure out why. So I did some random googling and typed in 02 mustang gt IAC valve and went to photos. There were several different photos of the 4.6 engine zoomed in on the valve, but I noticed that throughout the pictures were two different kind of valves: the one you see above, and one that looks just like the one above although it has a small black cylinder attached to it. This has something to do with relieving vapors I believe, not too sure. But this type of IAC valve came on the 91 and earlier gt's. But I decided to try it on my 2002. So I bought an IAC valve for a 2001 and slapped it on and perfecto!!!! Or ran like a boss. My theory is that since my car was manufactured 01/02, they (as in Ford) might have carried over the 01 valve until around mid year (06). Just my theory. But before you buy this valve, double check yours.

    Only buy foma/motocraft iac's

    Other iac's do not operate properly. Save yourself time and buy Ford IAC
