I got my e85 conversion done as well as some P&P heads with 1.8rr. The car was running great for about 2 days and then this morning it started to sputter really bad in lower rpm and as the day progressed the car only sputters in the upper rpm range.
My hpt is showing no misfires, and I just checked the plugs and wires and gapped plugs to .045. I just changed the flex fuel filter to see if the other one was clogged, and it hasn't made a difference. The car doesn't lean out when the sputtering happens and there is no loss in fuel pressure or boost. The knock will shoot up if you stay in it too long while it sputters. Anyone have an idea on what I should check next? Thanks, Andy C.
