just an update from me since this thread wont go away lol.

Mileage is getting worse, I've had an SES light come on 4 times with a lean code, and my drivers side floorboard is getting really hot like the cat is on the way out.

I have no idea if this is ethanol related, but it may be,

Station on 19 and Jasmine in NPR is ethanol free, I'm going there next tank and every tank after.
