its the 3rd trip to the dealer in 6 mo. Beginning w/a burnt rotor; ck eng light; scan codes 02 sensor; then cat+ muffler blew out from raw gas; recheck scan-intermittent stalling - spark plug wires; serpentine belt done; installed new cat/muffler; ck eng light-scan -no codes; #5 misfire after 2nd cat/muffler blew out; scan=crank sensor; stall interrmitant. Remains at dealer, placed a " co-pilot" + test driving to get some codes (codes not coming up).

I am not a mechanic, but it sounds like the pcm is intermittantly malfunctioning? Your thoughts? What is causing raw fuel to blow through cat/muffler? Thank you : roll:
