It seems to occur within 50 miles of refueling and at highway speeds. Also the engine is at operating temperature. When it occurs, the engine will not run over approx 2500 rpm and if it does reach 2500 it shakes violently until back down below 2500. If you pull over and shutdown, it will restart and run fine. No error code that I can read with my cheap device. Also no CEL. The violent shaking is really violent and it feels like theres a big chain attached to the axle stopping the car from moving forward.
