1996 Dodge Dakota. Engine stutters

[MRX37]

Okay exhaust pipe there's a little gray/black soot but I don't think running rich is the issue. Spark plugs I haven't checked yet, but, and I forgot to mention, the mileage is high, but both the engine and trans have been overhauled recently, so I doubt it's the plugs, but I plan to check later on.

Also, like I said I had this issue on my 92, and on it I did plugs, cap and rotor, fuel pump and filter... never solved the issue. Basically I am positive it's an issue with the wiring, or a sensor.

Should also mention I have receipts for the repairs done, that's how I know about them. Also I have another question:

I want to swap over the dash from my 92 as it's in better shape then the one on this 96. However the dash has the VIN plate riveted on it. If I swap dashes the VIN changes and that may cause issues. So should I leave the original dash in place or can I do something to swap VIN plates?
