Drove the car around today and it has gone BAD lean from the ethanol. A/F gauge driving around wouldn't even move to the green. I pulled codes and sure enough banks 1 and 2 lean. I need a quick fix such as an additive or an adjustment I can make. I have a track day at Nashville Speedway that is 180 bucks non refundable entry fee next Saturday so I have to go. I read someplace that an additive used for boats called starbrite (I think) works wonders for EFI cars. could bumping the fuel pressure higher (already at 35psi) and adjusting the timming help some? I know I need a computer tune bad but that will have to wait till I have time in August for Fun Ford Weekend.
