Seems to be running better and stronger after putting in about a half tank of new gas and driving a bit. It’s strange. I saw 0 knock, it’s a 91 tune on 93 gas, and I added e85 to be sure. Still had an issue until the new gas. Must’ve been some supremely shitty gas to still have issues.Could be bad gas, or low ethanol gas. Filled up recently with some E0 91 and was getting knock like crazy. Had to mix in about 2 gallons of E85 at 80% to bring it up to E18ish before things calmed down.
This was also after the first heavy rain in awhile here, so could have been an issue with their tanks too.
If it was a place you don't normally fill up, try topping off at your usual station and see what happens.
I’m still suspicious there’s another issue afoot since this happens more often than seems reasonable… but no clue what else to look for if there are no codes. Maybe I just need a carbon cleaning
