if my car is parked on a hill and i have to put it in reverse it does a really hard jolt or a kick. while im driving it does it again around 30 mph and again around 60 mph. sometimes if im at a stop light it kind of jerks as i start to take off.
The engine light was on and the car seemed to be running fine. That is when i went in to hook it up to the diagnostic machine. We found out it was the oil pressure sensor. You do have to order the part through GM, but it is only $10.00. my husband fixed it in about 10 min.

Flex fuel vehicles can develop fuel calibration issues resulting in illumination of the Check Engine Light and/or lack of power.
