Okay folks this one has me pulling my hair out. I'm working on a 2000 H1 Hummer with the 6.5 diesel in it. The problem is when you get it up to about 50 mph and keep the throttle at a point to maintain that speed it starts cutting out. It will act like it has lost fuel then will run for a second and then act like it has lost fuel again. If you hit the pedal it will run fine. I'm going nuts because none of the scanners I have access to have any support for the hummer short of global OBDII. Any suggestions would be greatly appreciated
