This bulletin applies to 2014-2018 Chevy Corvette vehicles equipped with a 6.2L LT1/LT4 engine.

A harsh shift and a sputter when applying throttle between 0 and 30% and a rough idle may be experienced.

DTCs P0101, P0171, P0172, P0174 and P0175 may be stored.

The cause may be excessive casting flash in the air filter housing near the MAF sensor.

If this is found, replace the air filter housing lid. Be sure to check for flashing in the new lid prior to installation.

Example of excess casting flashing in the housing.
