Do you guys come across bad gas (car) often? Been struggling for about a month. Car has been pulling timing on every hard acceleration and even on average driving.
I've cross-referenced my old logs from when everything was dandy, and my AFR matches, my MAF matches, my calculated load matches, the oil temps match, EVERY PARAMETER IS EXACTLY THE SAME, and somehow my car is detecting knock.

I've gone into the engine bay to check for loose thingies making false positives, everything is locked in. I've gotten fuel from 2 different distributors, both "92" octane.

I refuel my car at 25% remaining every time. How long do you guys think it would take to clear the system of this bad gas? Is there an easy way to purge the tank entirely so I can start fresh?

I have refueled 3 times since initial bad tank

Thanks
