2003 Chevrolet Silverado 1500 5.3L Misfire
I am posting this to help a friend at another shop. He has a 03 Chevrolet 5.3 that is missing out on cylinders 2 and 7 at idle. Anything above 990 rpm and it is running fine. After replacing the intake gasket and clearing the codes, the only code now is P0300....
