need some help. I have a 95 gt and when i set the cruise control it sometimes or most of the time will surge sometimes to the point of cutting it self off. Does anyone have any ideas on this? Thanks in advance for any help.

 

Start by pulling codes .

Does it run good otherwise ? Or is this the only time it gives you trouble, meaning only with the cruise on .

 

No codes and the car runs great otherwise. It only happens when the cruise is set. If you put you put your foot next to the accl pedal you can feel the servo moving in and out.

 

I'm not familiar with the SN cars, do they still use a diaphram and vacuum for cruise control ?
