Did you replace the fuel filter ? There is NO WAY TO CHECK a fuel filter. Because fuel comes out of the feed side of the filter does not mean its not clogged. It could restrict under pressure. I say , start by REPLACING THE FUEL FILTER. There is also a screen in the tank attached to the pick-up. It also gets clogged at times. Hope this helps.

Check the distributor shaft. They have a history of developing finite cracks that causes the condition your describing. Let me know if I can help you with any other info.

the dimmer switch would be where I would look first. See if the conditions change after turning the lights brighter and dimmer.

You definitely covered most of the bases. Considering all you've done so far, I would check into the fuel system next. First, how old is the fuel filter? Has it been changed? Yes, a bad filter can cause the problems your having. Next would be the fuel pressure regulator. You need a fuel pressure gauge to check it, which you should be able to rent from a good auto parts store. That will also tell you how good your fuel pump is, i.e. if the pump can deliver the necessary fuel pressure off idle. After that, I would check the injectors themselves for wear or blockage. A bottle of fuel injector cleaner in the gas tank would be a good idea, cheap, quick, and it wont make anything worse. If all that checks out, check your catalytic converter, a clogged or bad cat will also do what your describing. Good luck.
