2007 Jeep Compass 2.4L
The car has recently started developing a lurch when I back off the gas after accelerating. It usually happens at medium throttle or higher, like when accelerating up an on-ramp or something. It accelerates fine, but then has a single, brief lurch like the throttle gets fully closed for a moment as I slowly back off the throttle when getting to the speed I want, or get over the crest of the hill, or whatever. After the lurch the revs return to normal. It’s the same effect as if I quickly took my foot right off the gas pedal, then immediately pushed the pedal back to where it was.
It’s drive-by-wire. I’m thinking that a bad spot has developed in the gas pedal sensor. I probably won’t be able to figure out very much about it before I give up and take it to the shop.
- Before I start playing around with the pedal, are there any other obvious places I should be looking?
- If it goes to the shop, would this be a dealer-only option because of _____?
