Hi all, My jeep is running rough at idle and when trying to maintain a speed. Taking off it my hesitate for just a moment but then goes fine. its not until I easy off on the throttle and try to maintain a speed that it shakes and shutters or when I come to a stop. The jeep check engine light was on with a code P0300.
I changed the plugs, coil pack, ran some fuel injector cleaner, and even the catalytic converter ($$ not well spent there
Let me rewind a little... When I changed the plugs the #6 cylinder had a bad plug. The plug was wet and was obviously not firing. This led me to believe, after changing the plugs and the problem remained, it was the coil pack. Once that was changed and the problem remained, I got flustered and did a crappy evaluation and said well its the cat.
So now the jeep is throwing several codes and runs the exact same. The code are p0300, p0302, p2302, p2305, p2308, p2311, p2314, and p2317.
Any thoughts on this
Could it be the PCM?
