Well to start off the new years I had to have my car towed home with a P0306 cylinder 6 misfire. It all started after I hit a small pot hole on the interstate. I heard a pop on the right side of the car from under neath and the engine light started flashing and I pulled over at autozone and showed code P0306. So better safe then sorry and being the car shut my transmission down to nothing had car towed home.

I have replaced the plugs and wires with Ac Delco and reset the light. Ran coil test and they show to be good. Car starts and runs fine and engine light stayed off. Drove it down the road and notice after it got to 120 degress that if you press the gas down hard when going up hill it acted like it was missing and I heard the pop again from under the car next to the passenger side door but no engine light. transmission is shifting good so I dont think its that. Thinking maybe a damanged catlitic converter.
