Random Misfiring Vette

This bulletin applies to 2001-2013 Chevy Corvette models. You may encounter a SES lamp and a misfire condition, with DTC P0301-P0308 or P0300 only (random misfires on random cylinders).

If you run into this concern and normal misfire diagnosis does not isolate the concern, inspect the torque tube coupling for damage before attempting engine disassembly.
