yeah it is E-10 ethanol gas. and as well as other things my gas mileage dropped from 22-24 mpg TO 18 mpg around town. but what concerns me is the complete lack of power, as soon as i started up my car in the gas station with the new tank of 92 octane it ran like a champ again and is back up to idling @ 1000-12000 RPM instead of 700ish and jumping around. thinking maybe i should re-check the timing now that it has proper fuel in it and see if that isn't an issue.

and i am going to swap out the 02 sensor soon, as well as ditch the coilpacks for the plug/wire option just to be sure that my ignition isn't an issue. but i went through and unplugged the coil packs one at a time to see if one was not working, and they all were, it made a huge difference when i did that.
