miss fire maybe?

[coryH]

hey guys. well i have no clue what is wrong with my dsm. what a shocker . We changed a bad ECU, seemed to make the car run smoother but did not help the problem. when you get up to 4500-5000 in ANY GEAR at ANY throttle position it does it. Its like a studderbox and sounds like a hardcore misfire/fuel cut. The timing is bouncing around during the datalogger view when it happens. The only thing we havent tried is the CAS and timing. Any help would be greatly appricated. thanks guys!!!

What exactly have you tried? Have you swapped the coilpacks? Tried new ignition modules? Checked the plugs for signs of wetting or fouling?

i have tryd. coil pack, ecu, plugs, wires, ign timing. im thinking maybe its the timing belt is off.
