1996 GMC C1500 Sierra SL 5.7L Misfire
Posted to GM Driveability on 1/17/2005 31 Replies

Truck came in with cyl 5 & 7 misfiring. did some checking and decided to replace lower intake manifold gasket, since these are always going bad on these VORTEC motors. after replacing still had 5-7 misfire. all sensor signals looked good. Replaced gasket again...
