2003 s10 4.3 vortec intermittent misfire
Had the truck for about a month and replaced the cap, rotor, plugs, and wires mainly as preventative maintenance. On occasion it would start up and would have a solid miss and then come out of it but mostly start up with no issue. I could start it in the morning with a miss and by the time I leave work the issue disappeared. it's got a p0101 and p0301 and also throwing out codes for the upstream o2 sensor along with occasional p0300. I checked to see if a plug was fouled out and they seem fine and had a light brown color to them. Pulled the cap off cleaned it up and it was fine for a few days then went back to it. No clue if a maf would cause it or a coil. I've got nothin
