Bad Vibrations and Misfires

This bulletin applies to 2001-2013 Chevy Corvettes that exhibit random misfires on random cylinders, with DTCs P0301-P0308 or P0300 only.

If you run into this concern and normal misfire diagnostics do not isolate the concern, before attempting any engine disassembly, inspect the torque tube coupling for damage. Any such damage may have be the result of overly-aggressive vehicle operation.
