    Help- Same issues, same year, same model Indy 500 EFI, what was the end result of this issue...Did you just end up getting rid of the sled
    Very clean fuel, new battery, good fuel pick up, new fuel filter etc. TPS changed out, ECU replaced, same issues. This things driving me bonkers.
    starts, runs great at idle! Engage throttle bogs down. Pump the throttle and eventually gradually runs up at full throttle. stay at top end runs great, very fast. let it come back down to idle and bogs down at low speed. Added electric fuel pump inline to see if it made a difference...Nothing, same issue. It's not mechanical, I can unplug the ECU for a minute or two and runs great no bog. Then the very next take off Bogs again. The sleds like brand new with less than 1400 miles. Seat has no cracks, looks new so I kind of want to get up and running. Please MattyC reply with other info. ! Thanks!

    The 1992 is different then the later ones in the way the ECU powers up. What did you do? installed a inline electric fuel pump? If the ecu is unplugged the fuel injectors do not get a signal to spray so it would not fire and would die from no fuel.
