Actually the spark should be a big, fat, BLUE spark, not white. Put the Bosch coil in that you origionally took out. You could also have a problem in the ignition wires now. With a GOOD coil now you could have broken down the wires and now the sparks are jumping out on the wires and not at the electrodes. I think I am still on the right track as evidenced by the fact that we touched it (the problem) and corrected it for a short while. I don't think the fuel system could act "flukey" like this with a problem that comes and goes while working on the ignition system. Humidity can affect this greatly. Was it raining in your area today when you noticed the problem reoccur? On a completely different tack maybe the fuel filter is plugged up. Under high fuel flow conditions it can't deliver enough. With all the dirt and problems you had initially with the fuel system maybe you filled the filter up? Many times a problem with a car has several causes. When you fix one another shows up underlying the origional. You never notice it because the obvious one is hiding it. When you do the fuel system tests it is not under load so you wouldn't see a dirty fuel filter. This could also be the cause of your low primary pressure. Before changing shims (which is RARELY NECESSARY) I would replace the filter and cut the old one open.
