I let it cool off and still the same, I can't remember how long I was on the gas pedal, and I press the pedal all the way sometimes, when I drove it I was pressing the gas pedal and got no power from engine when it's on I press gas pedal and no response. I also have check engine light that came on, sorry but I don't have a scanner.
I still have the muffled sound, could it be that I stomp the catylitic converter?
