1999 Ram 1500 5.9L Sherrod conversion van with 75,000 original miles.
I was getting "Check Engine" and code P0753, something about Solenoid A that controls the lower gears. After a day of diagnosis, the Dodge dealer said I needed a new PCM (Powertrain Control Module).
Driving home after the PCM replacement, I discovered I no longer had cruise control. Otherwise the van ran extremely well on the 60-mile trip home.
Two days later, I took the van on an 8-mile jaunt to the park. Going there, no problem. Still no cruise control, but it ran great.
Coming home, all hell immediately broke loose. The van would go no faster than 30, then 20, then 15. Depressing the gas pedal seemed to have no effect. After 300-400 yards, it would simply start slowing down to 0. I would pull to the side, turn it off, restart it, and get another 300-400 yards of this fun. Several times it made a bizarre noise resembling a backfire. I limped home with the emergency flashers on, but it was frightening - twice it just stopped in the middle of busy intersections.
It was as though the entire fuel system had gone insane. I assume this must be PCM-related as well. Can someone more mechanically inclined than I am confirm this? I know the PCM must be programmed to the specific VIN; could the fact that this is a Sherrod conversion van be the culprit? Mechanically, it seems like a pretty standard Ram 1500.
Thanks in advance.
