When you take off after about 20 miles an hour the car will jerk a couple of times then seems to run smoothe as if nothing is wrong. The vehicle started doing this about two weeks ago and does not jerk every time it is erratic and I was wondering if this could be in the transmission or possibly a fuel injector problem
