Hi everyone! I have a 2004 GT premium Mustang Convertible w 50,000....My car stalls ONLY when the A/C is on, I took it to ford and they told me I have a bad idle control module so I had them replace it, driving home from ford, my car stalled at a red light A/C was on and now my check engine light is on. Ford Told me I needed a throttle body flush, so I had Firestone do that for me. Driving home again My car stalls with the A/C on and check engine light came back on. So I took it back to Firestone and then they told me the codes on the check engine light were telling them that my Mass air flow sensor was bad, So I had them replace that! The next day A/C is on and my car stalls again and check engine light is back on...I have taken it back to ford and now that are telling me I have one bad spark plug???? I am not sure if I should let them fix this, not only am I broke but really really annoyed! Please someone HELP!!!
2004 Keeps stalling PLEASE HELP!

If your check engine light is still on I would take it to an Autozone or an Advanced Auto and have them pull up the code. It just seems like you are chasing around something that might not be there. From there you should be able to get it to a generalized area rather than just fixing a bunch of random things.
It is just my opinion but it sounds like you may have a bad idle air control. If your car is stalling only when it is idling like at a red light or when you are just sitting there than that could be the problem. What it does is just bring the engines idle up as you turn on the AC so that the engine doesn't die out.

This may sound silly but how old is your battery? The iac will compensate for charging the battery and the addition of ruining the ac may be too much. I found this problem because I had similar problem to yours and replacing the battery fixed the issue. I use Motorcraft original battery. It should last for at least 10 years, $110 bucks. High energy optima only its good for 4 years and costs $50-$75 more, they are two different types of batteries. Mustang electronics are very sensitive to battery condition.
I hope its not my transmission! Cuz I dont have the money to fix that. However Im a little weary cuz Ford is trying to get me to change my spark plugs? But how does that cause my car to die when the A/C is on? I am tired of replacing parts and not having it fix the problem...And i had to replace my battery about a year ago so i know its not a bad battery.
I would get the check engine light diagnosed first ,could also be a high pressure switch or compressor clutch switch, I doubt a bad spark plug is the problem,get the code that is throwing the engine light on first!
If this happens only when the ac is on then its in the ac system or wiring related to the ac .

Your location says California? I'm guessing not, but you need to find someone local who know the cars and can trouble shoot without throwing parts at it. That can get very expensive and frustrating as you already know. Find a shop you can trust. Talk to friends and see who fixes their cars. It can be fixed, you just need to find the right mechanic.
