Is that why my gas milage went down?
Is ethanol bad for O2 sensors as well?

I originally blamed the tune ... perhaps it was the addition of the ethanol the car didn't like.
I haven't tried the 94 in the Fusion yet and now don't plan to ... I'll be replacing the 94 tune with a 91 tune for CAI ... yes Daniel I bit the bullet today and ordered the Steeda CAI with removable insert - Steeda says it's worth 8 hp and 10tq with the insert, and even more with the insert removed and a tune. We shall see.
