I have a 08 GXP 3.6L auto w 110k. The car has recently developed a part throttle stutter, hesitation at cruising speed particularly when going uphill. It will continue doing this unless the go pedal is depressed to accelerate regardless of whether it downshifts or not. Code P0303 (cylinder 3 misfire) code was stored. I erased it and drove it today. It still does it however the CEL has not come back on. I've also had the T/C light come on and the CEL flash for several seconds but not stay on. This may be unrelated as it occurs under hard acceleration but it doesn't seem that the drive wheels are losing traction. Ideas or suggestions?
