Why does my truck jerk at left turn and lose power

Hello, sounds like perhaps there is a concern with an anti-lock brake wheels sensor, tone ring or wiring related -- that's a total guess, but I can't imagine an engine or transmission concern causing any of these warning lights due to turning one direction. Use of a diagnostic tool capable of monitoring and evaluating the various systems of the vehicle is essential.
