no check eng lights, ran thru normal diagnostics including 5v ref at tps, compression good, injectors fine etc., This unit runs fine for a very short time, then it wont come out of an idle, bogs, and wont really go anywhere. you literally have to idle and tweak the throttle for quit a while and eventually it will go. When it does take off it runs great until you bring it back down to idle and coast around- then its the same thing over-no power, acts like fouled plugs but their not. If you wait long enough and tweak throttle eventually it will take off. Its a vicious cycle i cant solve. new plugs make a difference for about 10min then same thing. maybe internal water leak? Has anyone else experienced this with an RFI? thanks
