Engine Performance problem
1995 Dodge Ram V8 Four Wheel Drive Automatic 120000 miles
At approximately 60 mph on the highway my truck will hesitate under light loading. Power train will buck quite noticeably. Not sure if this is a power train issue or an electrical issue. This will occur while the accelerator is transitioning from power or to power. I have a 5th wheel camper and while towing this situation is greatly exaggerated.
I had an EGR code (32) on the PCM, so I changed the EGR valve. This code has not returned. I also have a 37 code, but I cannot find that code other than on a diesel engine. I have replaced the plugs, wires, distributor, cam pickup, and rotor to no change.
have the same problem?
