Sounds like your base idle could be really messed up causing your idle to hunt. try resetting your base idle to around 750-800. Idle Speed Adjustment

Check the tension of your throttle cable it maybe too tight.

i have checked the throttle cable, and its not doing any thing different when i loosen it, and if by base idle u mean the idle adjustment screw, then ive done that and the idle doesnt move. is it possible that i jump a tooth on the timing chain? or my idle control is fryed?

The idle wont move unless u do it in timing mode... follow those instructions

how do i do that
