I don't know why, but sometimes my throttle gets stuck and it is hard.....meaning when i give it a little gas it won't rev or go, so i have to gas it with more force for it to rev up and go again. anyone know why my throttle is like this?

 

I would make sure the throttle plate area is not gunk up. Use carb cleaner if necessary. Then inspect the throttle cam stopper set screw, and adjust if necessary. Only adjust to the point the plate is not sticking. However, if you have to make adjustment to the stopper set screw, you will need to re-adjust the TPS sensor as well, as the change of throttle plate position will throw the TPS setting off.

 

there was no adjustment on the throttle body. The only thing is is that i have a weapon R throttle rotor. I had it for a while, but since my motor has been out for 3 months, it is kind of sticky.
