vibration during acceleration?

[06cumminspower]

so you think it could be a flywheel? i kinda think its a fuel problem because it also has an eighteen k resistor mod on it and sometimes it does it only on hard accelereation but if you turn the dial all the way off or accelerate normally it goes away

sorry i meant ti be alil clearer. it did it before previously w/ the 18k but now it does it all the time when its off and not under any acceleration.
