Truck will slightly surge forward when my foot is on the brake as I come to a stop or as I release the brake before hitting the accelerator. Symptom occurs irradically and sometimes the surge is more pronounced than others. This is not an engine surge it is a vehichle surge. No codes are present. No mechanic thus far can offer a solution.
It is a engine surge. There is a service bullentin to reflash the PCM to solve that problem.
I fixed the problem believe it not by removing the rear section of the driveshaft and lubricating the slip yoke. I met a guy at Napa who said he chased this problem for 3 years. He was told all of the same stuff I've been told, transmission, rear end, spring hangers, fuel slosh, engine surge, etc. He said this fixed his problem. So I tried it. It worked like a charm. It has 100% solved the bump stop.
it sounds to me like the transmission is downshifting just before stopping into first gear and that change causes a surge. just a thought
