Limp Mode w/ codes - Tried multiple fixes / Searched

TPrelude-370z

Hey guys, sorry for the delayed response as I was on Vacation. So I burned the entire tank empty by just running it for hours at a time. I filled it with 100 octane race gas and 93 (only 4 gallons of race gas), and added heet (water removal product). The car slowly but surely started running a bit better and the rpms would go through the entire range but it was still far from 100% engine light still on. I let it sit overnight and tested it the following morning. Ran great, sounded great, but CEL came on even though things were smooth.

Went on vacation and came back.

Started up and purring like a kitten. Test drove and viola perfect. Been driving it like a champ the past few days and its about 95% normal. Only a small fluctuation in rpms (100 or so) but doesn't seem to be a big deal for now. Does seem to be idling a bit lower but again these are nit picking. Looks like it was water in my tank and bad fuel. I'm so grateful it worked out the way it did. If I took it somewhere, I would have spent a fortune for them to try and figure it out. Thanks a lot guys, you were very helpful.
