Make sure the initial timing is set correctly, just to be sure it is not causing some issue. Like I said, on my Firebird, it should be 0 with the brown wire disconnected. Consult your manual and set it accordingly. It may be fine at 6 but for now, everything needs to be at the specification to help eliminate variables while troubleshooting.

I did not notice that you replaced your plug wires. Mine developed a miss a couple years ago and it was bad plug wires.

Aside from that, I don't really know. I think the only sensors you haven't replaced are the knock sensor, map sensor, and distributor pickup. The map sensor will probably be the easiest to replace. A test you might try there is to simply disconnect and plug the hose to see if there is any change. If it is working properly it should run even worse. If there is no change, then it might be the problem. Make sure the hose is good, too.

Many times a vacuum leak can be a little more difficult to detect because the fuel injection will compensate for it. If that leak is in the map sensor hose or possibly even one teed into it, it will caues problems.

I don't understand why a laptop won't work. Are you saying that if you press the on button, it will not turn on if it's in your house??

Charlie, Knock sensor has been replaced, Plug wires 8MM are good, total rebuilt distributor. Haven't done the MAP sensor yet. Will try that next. What I meant on the laptaop was it will not get any reception from an outside source in the house. I would be able to use the program from the truck in the house but any other signal you would have to outside to use the laptop. G.S.

Oh, well you can plug a laptop in. You don't have to use the built in wireless. Also, the majority of laptops do not use an outside source, like a cell phone or satellite internet. They use a wireless source from within your home or a local source like a restaurant.

I finally hit on the problem; MAP sensor is the culprit. The only sensor I had not changed. Thanks for the suggestions to solve my problem. G.S.
