Alright, tried a new MAF, no dice. Anyone have a Tech 2?

Throttle body or TPS issues?
Fuel filter?
Vacuum Leak..a bad one will throw codes

02 sensor or Vacuum leak might be a culprit for loss of power.

I am thinking reset by removing the negative battery cable for 10 minutes then reinstall. Key on for 30 seconds. Start and idle 1 minute with everything off. Put in in gear and hold brake for 1 minute. Turn on Air conditioner and let idle for 1 minute... That puts it in a base strategy and should learn from there the proper air fuel / timing strategy.

OP have you tried this?

Yup, still nothing. I'm still hoping it's just bad gas.

I've never had an issue with their gas and use it regularly. Wasn't a tanker there filling the tanks by any chance was there?

Hopefully so, but I'd stay away from E85 anyway. Once things are normal you should expect to see higher MPG with regular gas.
