Here is what happaned, i raced a friend of mine from a 3rd gear roll. Right before i was shifting into 4th i felt a slight power drop, finished pulling 4th and slowed down back to 55. After that my car started to shake a litlte bit, then it got little bit worse. IT seems like every time the car is bellow around 2.5k it has a big miss. The engine shakes pretty bad. Once u get above 2.5k its kinda smooth, but you are still able to feel vibrations. ITs 1am right now, so i didnt check much, but so far no codes on the scanmaster, all readings are normal, o2 readings are fine, I checked the wires for burning, they are all fine. Pulled the driver valve cover off and found nothing as well, everyting looks normal so far. Any ideas? The exhaust note is not as loud or as smooth as it used to be, kinda seems like i am running on 7 cylinders.

Thanks for help.

maybe your optispark or detonation. Maybe it's that new cam of yours take it out and give it to me!

Check your springs closely...you may have broke one. I would also pull the plugs and look at each one to see if you have a problem with one cylinder or plug/wire.

Thanks
