hey this it my first time here I have a 1995 ram 2500 with the 5.2 and when I'm accelerating untill I hit 50 it stutters and misfires I've replaced the throttle position sensor, the map sensor and one other along with fixing some vacuum leaks, and replacing plugs and wires and it's still happening any ideas on what it could be?

Cap and rotor?

Plenum gasket. Any codes?

Does it stop shuttering at 50 all the time or when your not pedal to the metal. Does the shuttering seem to stop when it gets into OD?

It has a code at the moment because the o2 sensors not hooked up but it did it before i took it off and had no check engine light

It'll stop after 50 and only happens when I'm not bearly on the throttle or at full throttle. It only does it between the two when I'm around a quarter throttle to half

Just replaced it hopefully it helps

Plenum plate. Open your TB and look at the bottom of the intake manifold with a flashlight, I'll bet there's oil on it.

I'll take a look I gotta put it in time anyway so might as well check while I'm there

there was a little bit of dirt down one but that's it it
the replacement of the distributor and cam sensor that fixed it
