I have exactly the same problem on my '98 V6 AT.
I have:- replaced the upstream O2 sensors

- replaced the fuel filter
- inspected the MAF (it seems fine)
- tested the EGR valve
- looked for other intake leaks
all to no avail.
I now have an EGR gasket and a throttle body gasket at the ready, but frankly I don't expect them to make any difference either ... bummer.
I have similar problems. In my humble opinion Ford engineer's and programmer's (they call themselves that) engine management system and implementation of OBDII is the root cause of many of the problems. You need (we all do) to find a Ford technician that knows the Contour's design and maufacturing deficiencies.
I think we need to make up a 25 or more critical questions test for the mechnaics who are to work our cars so we can weed out the poor ones) and find mechnaics that can diagnose the problem properly the first time.
Any takers?
