Take it to a GM dealer, pay the man to put it on a diagnostic machine, and get a printout on the results. You will be far richer in the end rather than throwing money at it. All the codes you have will just give you an idea what's wrong. 1 or 2 things can produce several codes but can't tell you what the problem is. The diagnostic machine will pinpoint it. Trust me, I've been there. :D

I would check the power feed for the ignition and the engine grounds first. All those codes make me think you have a ground missing. You have conflicting codes, that is usually a power or ground issue. I have see a bad alternator that is leaking ac voltage also cause these types of issues. You can prove it one way or the other by pulling the belt. My be is a ground issue because after you replaced the dist it worked for a while.

The diagnostic machine does not pinpoint the problem. It is the tech using it that does that. The codes and the #'s don't mean anything if you don't have the skills and training to understand what they mean, and how they can interrelate.
