P0300 code I 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. |
300 is misfire but not a specific cyl. 0301-0308 would be cyl specific There could be several reasons for a 300 code. |
Random misfires, if i'm not mistaken, can be tuned out. Back in the day I had a very small cam that would cause me to throw this code. Had it tuned out. No issues after that. Hope someone can shed some more light for you, but I do seem to remember that, at least in my case, it wasn't a cause for concern. Good luck. |
