^^^ I wonder if a sloppy t chain could cause the same type of "spark scatter" symptoms?

I had the very same style truck years ago with the exact problem. I couldn't figure it out, so I took it to the dealership. They said it was the distributor drive bushing was worn. If that's what they replaced, it fixed the problem. Ran perfect afterwards. THIS Real common on the OBD1 magnum engine trucks , And its really common on a 3.9 V6. ^^^ I wonder if a sloppy t chain could cause the same type of "spark scatter" symptoms? MAYBE, but not likely.

This week I plan to do both of the things suggested. EGR and distributor bushing while I am working in that part of the engine. One question, what tool do I use to remove the bushing? We had the Mopar tool at the dealer as they have a tool to remove the bushing and to install and burnish it. But I dont remember the part # off top of my head as its a Miller tool. The dealer should be able to give you the # or it should be in the service manual. Ron

Firing order and (very odd looking) officially revised ignition wire routing to prevent cross-fire between cylinders 5 and 7 http://dodgeram.info/tsb/1998/18-48-98/18-48-98-v8.htmNote that the ignition wire routing for cylinders 6 and 8 looks exactly opposite of what you would think it should be.

yes push the bushing sideways & see how much radial play it has. EDIT meant to say push the shaft sideways to see how much play the bushing is allowing it to have.
