2000 GMC Sierra 1500 SL 5.3L Misfire, MIL Lamp on
Posted to GM Driveability on 2/13/2003 13 Replies

This is the first time we have seen this truck. We have swaped coils,& wires to see if problem changed cyl,s. It stayed with # 4. This has plastic intake. Could the intake be cracked inside.

Thanks Pete
