I need HELP!!! My 97 ram 1500 5.9L 360 4x4 is running weird. When I put the truck under torque ( going up an incline) it wants to jerk and shut the truck off. If anybody knows anything about what's going on please assist me. I replace both axle fluids, along with the transfer case fluid. The universal joints on the front drive shaft went out so I replaced them. After putting the driveshaft back on, I noticed a motor mount was loose so I tightened it up. The truck didnt start running weird till I replace the universal joints.

 

I doubt the drive train work has anything to do with it. I would start with a tune up and NTK O2 sensor. Take the IAC valve out and clean it and the passage in the throttle body. This could also be your plenum gasket and or catalytic converter plugging.
