Same thing happened to me I installed the walbro 255 pump filled it up to e60 tried flashing my car to bms e85 flash and it wouldn't work so I was stuck with all this e85 running it on jb4 so my car was running dangerously lean I started getting misfires on 3 and 4 cylinders the same day. My suggestion is to drive normally do not go wot. Burn a couple gallons off then replace with 93 to balance out the gas with the ethanol. As soon as I did that the misfires went away. So im not 100% positive the extra e85 caused the problem or just uncovered my weak coils but it worked for me . Good luck bud
