The misfire is causing the hesitation you just need to find out what’s causing the misfire. When one or more cylinders stops firing, the power cuts, and the vehicle hesitates under acceleration. The idle is low, not sure what that could be really.Įngine hesitation, almost by definition, usually goes back to a misfire in one or more of the cylinders. When it’s not that they have no idea what it could be. Most mechanics first think it’s the motor mounts. I’ve replaced the spark plugs, cleaned the throttle body, replaced all 4 motor mounts, ran some seafoam through it.

It’s not as bad when going fast on the highway but it does still happen. It does this when in a fixed gear, like 2 or 1. When on the highway and turning off cruise control, I get a pretty big jolt. If I very slowly accelerate or decelerate it does not happen. It almost feels like something is grinding. There is also a vibration I can feel in the acceleration pedal. It’s also a little delayed when accelerating. When I release, it’s one jerk followed by two smaller ones. When I press the accelerator, it’s one jerk. When I swiftly press or depress the accelerator I get a pretty sever “bump” or “jerk” feeling.

No one can tell me what is causing it, not even the dealership. Where to start with this - First of all, 8 mechanics have looked at it.
