Hey Fellas
I've been traveling around the country in a '84 F250 with a pop-up camper on the back for the better part of three years. I have the 7.3 swapped in with a banks turbo. ZF5 manual trans. I also have an electric fuel pump swapped in. Currently hanging out in Jacksonville doing a few repairs on the truck / camper.
I've been stumped by a lope / surge that occurs intermittently, but most frequently during a cold start. It does not happen every time and it rarely happens once the engine is warm. It goes away immediately when I give her gas, and has never occurred at any time aside from start up. Here is a video.
I've been doing some research on diesel forums and on Youtube and it seems this type of problem presents itself in many ways, and the solutions are equally varied. I've seen lope / surge problems fixed by replacing an ICP sensor, tach sensor, neutral safety switch, dual mass flywheel, chasing down an air intrusion... the list goes on.
Does anyone on this forum have guidance for me? Does anyone have experience troubleshooting this type of issue, and could offer some advice on the best place to start?
Thanks.
