I'm Awesome
97 Chevy 1500 5.7 vortec 250k miles. The other day I started it and it has a rough idle and backfire at idle or low rpm drives pretty good but not 100% recently changed plugs and wires and fuel filter 2 new batteries new crank sensor. Started shooting single po300 code that said random/ multiple misfire. Very generic code I know right. any suggestions?
