I have a 98 camaro tuned by speedinc with various bolt ons and ms3 cam, I hit it one day for about 3 or 4 seconds and my car spudders now from time to time cold and alot when its hot. It feels like a dead miss i checked my parameters with the snap-on modis, both banks of injectors are at 3.2 @3000rpm i dont have a wide band or anything but my O2s are reading ok at 3000rpm. a little more rich at idle though, no missfires even when it does it. does this sound like spark plugs or coil packs?

Start by pulling the plugs and looking at them. They can tell you a lot.
