vehicle makes jerky stutters
07 DODGE RAM 1500 3.7 LITER vehicle starts to stutter while in cruise control or running at steady speed of 65 and starting up hill like it trying to decide to kick down out of OD. SO I PRESS ON GAS AND VEHICLE KICKS IN AND STUTTERING STOPS
Opening up the throttle diminished vacuum need. I suspect that you just have a vacuum leak and it might be at the cruise control unit.
