Question about 1988 Ford F 250
Starting the truck is no problem but getting going is the problem. When you accelerate the truck with almost jump and stall untill you reach 25 mph. The rpms go up and down and sometimes it will completly stall out untill you reach that 25 mph. It has also stalled out at a stop light. What the hell is going wrong?
If it's a 7.3 deisel, your timing could have jumped one tooth or your injector pump slipped one way or another. Pull your pump, lines and gear and engrave a line straight up from the timing mark so you can see it when you reset the timing gear.
