Filled up gas tank....now CEL and misfire at all rpms Yea.......so filled up with 93 octane at speedway this morning, 5 mins later driving down the highway, im noticing im gettin unusually good gas mileage, then I come to a stop......and feel the misfire, feels like im in DOD mode at all times, next ignition cycle, CEL comes on, bout to get it scanned and see whats up, might try the heat additive and octane booster to counter bad gas if that us the cause.
Any other ideas??

Speedway a low-end station like Raceway? Could be very bad gas, happens a lot at 'cheap' gas places. My wife used to get cheap gas until she got a bad tank, now she spends the extra couple of cents a gallon. You also could've pumped in some trash if they were low.
Of course, I could just be talking out my *** like usual.

tech i had scan it suggested adding heet and an octane booster, and just driving it until the tank gets at least 1/4, then refill. Probably gonna need new plugs too, bet #4 is already fucked
