Long post, here we go. Car is running lean on bank 2. Fuel trims for bank 2 are crazy high (+25). Car ran great at the end of the season last year. I swapped it over to 93 pump gas and drove it a bit through the winter.
The season is upon us here so i swapped back to e85. Did a few pulls and logs everything seemed alright. Had some belt slip so i swapped belts, and did another pull. Fuel pressure was down on this pull so i honed in on the fault fuel pump. Swapped it out for one i had laying around. Fuel pressure stays good now. Problem is fuel trims are out of whack (+25) and its breaking up bad. Its only on bank 2. Cant find a vacuum leak anywhere. Im at a loss with what to check for.
Ive swapped 02 sensors from side to side to see if probelm followed. It didnt, it stayed on bank 2. Im getting no other codes. Thought maybe it was bad gas because the e85 i put in it was what i ran at the end of last year, but it ran fine minus having some belt slip. I pumped out the tank anyway and put fresh fuel in it to no avail. Everything i search says vacuum leak or fuel pumps. But fuel pressure stays good and i cant find a vacuum leak anywhere. Any help or advice would be appreciated.
