Car Dies

I had an 8lb fidanza flywheel in my 1992 GSX, and the only time I had problems was when i literally revved the engine up, while standing still. the RPMS fell so fast the engine couldnt catch it. But other than that, I never had problems like you are describing. What is your idle set at? If its really low like 500 rpm, sometimes the engine has trouble catching when the revs fall (at least in my experience).
