    Default Engine Flooding

    I'm having a constant problem with my oil filling up with fuel (roughly a half gallon after less than an hour run time). Does anyone have any suggestion on what might be the problem? I've leak down tested the cylinders and I have less than 20% leakage, so I don't think it's the rings. 347 CI, 13.1,CR, Holley MPFI 66LB injectors running on E85.

    Which Holley EFI fuel injection system is this? Stuck injector? Also, read this: https://forums.holley.com/showthread...400#post104400 (MSD Rev Limiter Verification Disable)

    Would that cause the engine to not be able to rev past 2800 RPM?

    I guess if the spark plugs are fuel saturated (or misfiring/dead cylinders), then yes.

    I'm using the Holley HP Multi-Port EFI with the 4 barrel EFI throttle body. I'm also using the older style 6AL with the removable chip, so I don't think I have to worry about it having a rev limiter internally set on it. But I wasn't able to find a base calibration that was inline with my engine, so I downloaded the Global File called 330 40 psi turbo because it was the only one that seemed somewhat inline with my engine set up even though I'm not running boost. Do you know if there is a Global File that would be closer inline with my engine.

    Why would you start with a Global File for a boosted engine when you're not running a boosted engine? What MAP sensor are you running?
