I fixed the other code my car was having and now today this one came on twice i cleared it each time what is it and how can i fix it, the first time it came on it was at the track today then later when i was getting on it on the streets, also i was running 110 race gas do u think it could be from that

 

Def from the high octane gas

 

ok cool that makes me fell way better

 

the gas make any difference w/o tune for it

 

There's a word missing.

 

if felt like it couldnt really tell cause at the track my clutch was totally slipping 1st and 2nd gear, it made my exhaust backfire a lot more than usual
