Having problems with your 2000 Chevrolet Silverado 1500 ?
2002 Tahoe 5.3, under a load I get a multiple cylinder miss fire code. Engine has never stumbled or has a miss in it. This happens only when under a load like pulling my travel trailer. Driving down road and not under a load it is fine. It does have a bad O2 sensor I need to get taken care of but would that O2 sensor cause the multiple cylinder miss fire code? What else could be the problem. New plugs in it now. cy
