I think that you should address this logically, using proven trouble-shooting procedures as laid out in the GM eSi service manual. If you are going to turn screws on this ride, it's crazy to do so without it. The way to address this is to address the most problematic code first and using the flow chart in the service manual, eliminate the possibilities until you hit the problem. With that said, my first question to you is do you have the service manual? If not, shoot me a PM. That's going to get you moving in the right direction so that you are not GUESSING on a fix for your issues.
