If you have the time, maybe you should check for power to those cylinders' injectors/plugs [light bulb test or multimeter's voltage]. Their resistance checked out, so maybe it's just the power/signal. It does seem like a PITA, if not already, to continue testing, but you're so close! The price for a mechanic's service seems scary [at least for me!!]
Let me know what you think yeah? Just throwing this out there as an idea hehe.

Well, I'm not concerned about the mechanic's price. He's my neighbor and he'll just make me do the work using his high tech equipment while he watches and advises. He teaches auto mechanics at the local tech college. I just don't ever have him do any work for me because I have a lot of mechanical abilities myself. But he does have a big nice shop with a couple of lift racks in it.

Anyways, as far as ignition I have either replaced or tested everthing there is. I tested the pt today and it was good. I think it was cylinder 3 that the plug looked so fouled in. On your suggestion about the injector harness check, I guess I could go get a noid light to test the injector harnesses themselves. It tests to see if each injector is getting pulses of voltage.
As for fuel, I don't know of anything else to check. I can't believe the pump could be going out since the car will run it just won't run right. If the pump were going out it just wouldn't run, period. I don't know man, I'm just getting sick of testing/replacing things and always coming up short. I hope that I am close to the end like you said.
. Anyways, I'll post back tomorrow night after I check the injector harness.
