THE CATALYTIC CONVERTER WAS RATTLING REALLY LOUD AND I ASKED MY FRIEND WHAT TO DO. HE TOLD ME TO BEAT IT WITH A HAMMER AND W.O.T. THE ENGINE TO BLOW ALL OF THE DEPOSITS OUT OF THE TAIL PIPE. SO I DID. THE RATTLING STOPPED BUT AS SOON AS I GOT ON IT GOING HOME I NOTICED A DECREASE IN POWER AND HAD TO ACTUALLY LET OFF THE GAS FOR THE TRANNY TO SHIFT FROM 2ND TO 3RD! IM THINKING MY MUFFLER IS CLOGGED.... I HOPE SOMEONE KNOWS HOW I COULD FIX THIS PROBLEM WITHOUT REPLACING THE CAT OR MUFFLER. THANKS!!!!!
I HAVE A 1999 PONTIAC FIREBIRD (V6) WITH A BACK PRESSURE PROBLEM?
