Can anyone help with this problem? I have an 83 E-250, with the 351/5.8 engine and the van had started bogging/stuttering when in gear. Power decreased. I just changed the plugs/wires. The new plugs carbed up very quickly and it sounds like I need to adjust the distributor/timing a bit. It feels like the van has far less power and is still bogging, though less than before.

Does anyone know where the bolt is to loosen the distributor so I can nudge it a bit? Does it seem like the timing might be an issue? I have good compression at every cylinder, new cap/rotor, plugs/wires. It sounds like normal (which was always very smooth) when in park and I rev it. But when I put it in gear and drive it the bogging starts.

Any advice is appreciated.
