Hey! I'm new to this forum, and have questions I really could use some help with. I have a '99 GT, just purchased it 3 months ago. It does not run like a GT, for sure. I know I'm used to cobras, but this car is holding back. First thing, the idle is extremely irradic, sometimes going to 2000rpm then below 500rpms and dies. It only dies with the a/c on, but idle is always crazy. The engine is running real rough, too. We think it's the same problem? What weve done so far is replaced the fuel pump, fuel filter, and all the plugs thinkin that was it. Nothing has fixed the problem. Any guesses out there? Please help! Thanks!

Is it throwing any codes?
Reset the ecu by disconnecting the neg. lead on the battery for a couple hours.
Check plug wires/connections.
Check for moisture in the plugs/holes
Clean/replace air filter
Run some injector cleaner
Replace PCV
Clean IAC
Replace EGR
Try those one by one and see what happens.

Absolutely! Get it "fogged" if you think that's it but you can't find it. I've had that and it really messes up the car. At idle it's all over the place.
