This bulletin applies to 2001-2013 Chevy Corvettes that present with a P0300 random misfire on a random cylinder. The vehicle may have P0301 – P-308 or P0300 only.
If normal misfire diagnostics do not isolate the problem, before any engine disassembly, inspect the torque tube coupling for damage. Excessive play in the coupling may be responsible for the random engine misfires.
