I checked the power valves and cleaned them up they were sticky and I got a little better response but still bogs in mid range. I,m rumming ethanol fuel right now, and the the plug for the fuel (if it is a small blue plug on the ecm with 2 wires) is plugged in right now. Is this the right plug for ethanol or not??? does it make that big of a performance difference??? one other thing, how about the secondary clutch should the belt be flush with the top or should it be above????
