Well, I got the timing chain off today and I about crapped my pants! It was so wore out that I could almost touch the two sides together! A twenty year old truck still sportin the original timing chain right down to the nylon gear (still intact no less). I ran out of time today getting it back together so I don't know if it has cured my problem, but I'm sure it will run a hell of a lot better. There's no vacuum leaks, the computer is under the fender, and it's been running like this since I got the truck two years ago, but it's been getting worse in the last few months. It just kills me that my beloved mopar truck has no power, so it's time to do something about it. I'll let you know tomorrow how it runs.
