'95 90qs: Cut Out, etc. UPDATE

[Dan Z. Johnson]

Thanks for all the quick and detailed responses. I changed the two O2
sensors yesterday (with the generic Bosch plug from Blau). The car ran much
better, but, alas, it did not solve the problem. I reluctantly left the car
at the dealer (Holbert's in Warrington, PA) yesterday evening. I say
"reluctantly" because it died in their parking lot. They suspect a bad fuel
pump. We'll see what happens when the car surgeons are finished.
