Ok, it all started a couple months ago when my engine was ticking loudly. I figured I'd check the timing to see if it was firing wrong. I checked it and it had to have been around 20 BTDC. At the time, I incorrectly assumed that it was supposed to be at 0 TDC. After changing the timing, the sound went away and that's when I noticed the 15% (or so) lack of power and poorer fuel economy.

I wised up and realized it was supposed to be at 5 BTDC. Ever since then, the acceleration has been extremely choppy. I can only LIGHTLY accelerate and even then it's not very smooth. I'm running out of ideas of what it could be. I'm pretty sure it's at 5 BTDC, could it possibly be incorrect? I thought I may have switched the vacuum hoses on the distributer, but I don't think that's it either. I would GREATLY appreciate some suggestions!

I have a 1991 4x4 PU 22re.
