Bucking when apply throttle from low speed
I have a 2007 jeep compass and the issue occurs when im at low speeds (>25mph). When i am coasting below 25 and I apply a bit of throttle the car bucks/shakes. This happens no matter how much or little gas i give it, even if I smoothly apply gas. I also notice this happens when the car switches from open loop fuel setting to closed loop fuel setting (I've been driving around with a bluetooth OBD2 adapter connected to my phone to get mpg and stuff). Not sure if this is common or not happens almost daily. does not happen at higher speed.
