Fuel Pressure and Scanwest....That is a puzzler....

Thanks for the great comments Aaron and Steve!
Steve, I have not checked or thought of the fuel pressure because the code repeatedly said the fuel mix is too rich - but, I can see how this can happen: if there is some "battle" between the computer telling the system to inject more (thus the occasional spurts of power and the rich mix error code) and the pump that is exhibiting chronic insufficiency. I suppose as a diagnostician I would have to question the reliable starts and also those mysterious "no problem" two miles after the computer loses it's memory.
One interesting observation I made when I was erasing codes (and I did it several times with the engine running), was that the revs would immediately go up and stabilize right after I erased the codes but then start bogging down after I tried to press the accelerator.
Aaron - I believe that you work very close to where I live, I gathered that from your previous messages. As my time is very tight, I wonder if you would mind if I drove up to where you work and point to the exact place where to make the pressure measurement. It would be awesome if that could happen! I may not be able to get to it until the weekend, but basically I live a few blocks away from Magnolia store. And yes, you were right about eliminating the TCS - my 9000CD doesn't have it.
