Check the Simple Stuff First

Owners of a 2010-2013 Chevy Camaro, Avalanche, Corvette, Express, Silverado, Tahoe or Suburban may complain of an SES light and engine misfires.

Upon inspection, the technician may find DTCs P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307 or P0308.

This may be the result of a loose spark plug wire at the ignition coil.
