Hello all,
Last night I did a track night and experienced a misfire code.
A little background....... My CEL light stays on because I do not have the cats on (codes P0420 and P0430). I just leave it on no big deal. what concerns me is when I am really pushing the car hard it starts running rough and the CEL begins flashing. I noticed then then Bank 1 was running lean (20:1 or around there) while Bank 2 was normal (14:1).
In between sessions I looked quickly at the codes and saw a misfire code. I was in a hurry to get back out there so I quickly cleared them and went and added 5 gallons of 100 octane fuel thinking it could have been poor fuel.
Next run had it again. It sounds terrible and runs rough and then would straighten up. When I got home I read the codes again and there was not any misfire codes..... ? just the usual Catalyst codes.
I have read about the O ring fix and crankshaft sensor relearn. Is the poor rough running associated with this problem? Or am I perhaps dealing with something different? I was running the track key.
Thank you, Keith
