just got my 94 trans am lt1 back from paint, and its running horrible. never had a problem with it before. its a 6 spd also.

While idling it idles very rough, like its not runing on all cyldr's. also i can take off from a dead stop in 1st. have it floored and it barely goes anywhere, and once it hits about 4 grand it cleans out and cracks the tires and pulls hard like it should and i shift and its fine. or driving at 55 in 5th gear the car studders and feels as if it is loading up and shakes/chugs.

also when idling the car jerks around and everyting shakes aswell. I am not sure what it is. figured i would ask before i spend a ton of money on new parts. I had just put new plugs and wires in the car. its wierd cause one minute it runs fine and the next it runs horrible.

could it be either 02's, opti spark, fuel filter, injectors, Plugs wires (again). car has 77,900 miles on it only to. thanks for any ideas???

no codes have came up so far. i found the IAC and cleaned it, was a little dirty, but still no help

Sounds like possibly a loose plug wire. Or two... if nothing else changed but the paint. How thorough was the paint job? Anything they painted under the hood or was there body damage they corrected that might have required partial disassembly? If so, where on the car?

no nothing was damaged. and under the hood didnt get re sprayed at all. i checked the plug wires. all seem to be intact just fine. on both opti and the plug end
