Theres a recall on that problem for the 99 model year. I think it has something to do with the intake and some updated computer calibrations. Give Ford your VIN and they can check to see if the problem has been adressed on your car already.
I do believe that was for the cobra's.. They weren't making the power that the were rated at.

I have heard this also. But I plugged it in the Ford site and it said no recalls.... IDK. We will take it to a dealership and see what the say. It happened on the T-Bird too.

You could also take it to a dyno and see if you are making the power you should.... That wont be able to diagnose any mechanical problems, but it will give you peace of mind knowing if you are making the right amount of power or not... Also, what did you drive before the Mustang? I used to have a 98 GT before I got my 01. I thought my 98 was fast but when I first drove the 01 it felt like a completely different vehicle, much faster...

Was definatly the 99 cobra, not the GT that had the recall.

I would try to replace plugs/wires/fuel filter. New air filter or clean the air filter depending on what you have in it. Run some fuel injector cleaner through it as well.

Try those and see anything changes.

Did this year have problems with cracked intakes? I believe so, because I remember getting the class action suit notice on my wife's Bullitt, and it did mention '99. A cracked intake sounds like a likely culprit, that would give you the symptons you describe, and it's a free fix from the dealer.

I checked the VIN on the fordmainfoldsettlement website and it wasn't on there as one of the plastic defected ones. Any other ideas? Could it be a plastic one but not be listed? If so could I still get it fixed for free from a Ford dealer? Thanks.
