2004 GMC Sierra 2500 SLE 6.0L Misfire
Came in with a P0300. checked it with the tech2 and ended up changing the MAF(gm part) changed spark plugs and wire set ac/delco. Still had a P0300 with all the misfires on the left side of the motor. Changed the wire harness to the coil pack on the left side....
