Have you checked fuel pressure at idle and 3k TO 4K RPMS? I once took a crown vic to a local dealer, wanted $1500 for new cats. I did a fuel pressure test, 15 lbs at idle, 0-5 at 3K RPMS and went to 0 lbs. when punched accelerator. Was a $6 fuel filter.

This is on the air/fuel sensor that is mounted in the exhaust manifold right behind the radiator. You will need to remove a heat sheild to see it but you should see the wires coming out of it. Also a spiecial socket is needed to get it out without damaging the wiring.
