Todays helpful how to video will be showing you how I had an issue with my f-350 same as a F-250 Powerstroke I would sometimes not move any at all when giving throttle, occasionally I could hit the throttle and I'd have only Idle or very little power with the old 7.3 or dead spots in the throttle, find out if it was the fords IVS (Idle Validation Switch)? Was it the TPS (Throttle Position Sensor) or something else?
