2004 Isuzu NPR Diesel - Two problems

1: When crusing on the freeway and I try to just maintain a certain speed, it gets real ******" back and forth when i let on and off the gas pedal. When using the cruise control, i dont have any problems, but when I push the control to slow down or speed up, it still****** once each time.
2: Similar to problem 1, when crusing around 20-40mph and i hit a bump, the consiquent bouncing causes my foot to***** on the gas pedal, which causes the******** again. And once again if I use cruise control in bumpy areas I have no problem.

I think it has something to do with the accelerator pedal or something. Any helpfull advice.

Check the throttle actuator control module and the accelerator pedal position sensor
