Mathew441 Posted August 19, 2020 Share Posted August 19, 2020 Weird one here to me. 25 MPH or less or at a stop and go engine has power loss on right turns only. Slowing to 25 MPH to initiate a right hand turn, shift to fifth gear, and engine stumbles like fuel starvation. Stopped at a light and turn right, shift to third in the turn, loss of power. Mind you, this is only in the right turn, straighten up, slowly powers back up. No engine codes on the diesel laptop and all new filters.
