I have a ford ranger 2019 4x4,it would jerk when I was going at low speed and on high way it would run well. A mechanic said it need it transmission oil because it was low. Once he filled it I ran it for a day and code P0402 excessive gas popped up. I had also another mechanic check it’s and said pcm was bad.
