    If it is fuel injected mine did that when I had an injector stick open and it basically flooded at low RPM and ran fine up high.

    Sounds like a fuel pump to me.....if it won't idle but runs fine when at higher RPM.

    Fuel related at least, maybe clogged filter....

    If its carb'd, I would guess stuck float in the up position, flooding it at low rpm, but rev it up and it starts to clear its throat. TAP, not beat on the carb by the fuel inlet to maybe unstick the float. WHOOPS- I mean stuck in the down position so fuel keeps flowing into the carb. Is there a strong gas smell, or a puddle of gas round the carb?
