Yes, How did the plugs look? Were any of them particularly wet or white? If your getting a jerking out of it when accelerating the problem is likely a misfire. Does it have and engine code? Check the plugs again, the gaps might be wearing down. You may need to do a "tune up" (replace the plugs and wires). I would start there and then replace the coil pack if the problem persists. Let me know
