Well it didn't fix it. Still running like poo...

Since I didn't hear back from you, after the new distributor arrived, I figured it must not have solved the problem.

Yeah sorry, I didn't get the new distributor in until today...
I took the catalytic off and looked inside to see if maybe it had melted and plugged the exhaust, but no go. I also replaced the fuel filter, still no change. Checked the timing again and it was still bang on...

I'm going to try a fuel pressure gauge on the output of the fuel filter and check to see if the pressure is correct.

Well I checked the fuel pressure and that's good. Checked the valve clearances, and those are good. I checked the timing once again, and that was spot on...

I'm at a total loss. I've go outside to work on it every day, trying something different, but it just doesn't change anything. What bugs me is that the computer isn't giving me ANY codes for what's wrong...
Could a sticky valve cause this? If so, how does a car run with a sticky valve?

Are you away txgreasemonkey?

Your situation sounds like a very difficult one. Without being there and, based on everything you have already done, I don't have any great ideas on what to check next.

Well I eventually broke down and paid someone to come take a look at the car. As it turns out, I had 2 cracked spark plugs... It was only running on 2 cylinders. Replaced the spark plugs... ran like a charm!

After all that you had done, I knew it had to be something unusual. Glad to hear it's running well.
