My '92 400 se runs great and accellerates fast right up through 80 mph! the problem is that when i am going about 40 mph , and i crack the throttle on and off, sometimes the engine will cut out, like it lost fuel, or the air fuel mixture is incorrect. it feels like i am running on 4 cyclinders for a moment, and then it will begin running fine again. got any ideas? thanks in adavnce. i have greatly appreciated your advice in the past. thx, mike 602 616 2974 phoenix.
