Sharky92s | 10-12-2018 01:14 AM | P0300 code have a 2006 CTSV, I have kooks long tubes, high flow cats, running ngk 7 spark plugs as I am tuned to run a 75 shot. Car has been on a trailer for about 2 weeks as I have just moved cross country. Went to drive car to gas station and started misfiring terribly bad, I have never had a problem before with the car. And it just started throwing a P0300 code. Pulled all the plugs and they don’t look too terrible and wires look fine. I am about to replace all of them. And every once in awhile I will mix a little bit of 110 with 93 gas. I know it’s scrabbled but any options would be awesome. |
