I was just driving my car up the highway and all of a sudden I could feel slight vibrations I figured it was a suspension problem. The car has ben running perfect new tires New plugs Rotor cap wires timing belt water pump pcv everything new. Under slow acelleration and idol it sputters and hesitates a bit up hill. The more throttle the smother it goes. I noticed an exhaust leak in the back of the muffler where rhe tail pipe connects above the trailing arms . Any chance that could cause this problem??you cand definitely hear the leak at that spot and feel with hand. It wasnt this loud this AM

Yep misfire. No conpression. I guess i blew a exhaust valve. Gotta pull the head yah
