Driving the last couple days the TPS had started to hit the DC max and min limits, with it being bad this morning. Tried to recalibrate the APS and TPS and experienced this when calibrating the TPS https://photos.app.goo.gl/Sa1ndHM2Gw1fbMdt8 Any thoughts on what could be causing this? Sounds like the throttle is bouncing on itself. Haven't had time to grab the tune or log yet, just wanted to get people's thoughts while I finish the work day and get ready to tow it back.
