The EGR will not cause this issue, this sounds like the Catalytic Converter was not hot enough, another trick that worked for this kind of fail was a fresh oil change, make sure the engine is up to normal operating temp, which would be just short of 1/2 scale on the temp guage, if it runs cold replace the thermostat, I did smog tests for 30 years and these are the things I did to get cars like yours to pass given the test results you gave for the tailpipe.

The EGR, or exhaust gas recirculation valve, takes inert exhaust gasses
drawn from the exhaust system and reintroduces them into the combustion
chamber through the intake manifold. This process lowers the peak
combustion temperature and helps combat the formation of Nitrous Oxide
(NOx) in the exhaust.

SOURCE: EGR VALVE ON 96 FORD PROBE SE
If it's a 2.0L, 5 speed (1994-7) there are two DPFE solenoids (both w/ 3 vacuum ports) near the oil filter, which control the EGR valve. They are discontinued and impossible to find except on junked cars. (FORD #'s K5T44093-4)
I have to junk my 1996 Probe if I don't find them - Missouri emissions.

1st of all when Ford started out with putting "EGR's" on those diesel engines, they rushed it and are nothing less than a pain in the ***! i recommend having an EGR cleaning service performed by your local Ford dealer, i know they charge up the wazoo, but they're the best people to perform the service period.this is a VERY common problem with those engines and that service is "supposed" to be performed every 30K I believe. i dont recommend attempting to remove and service it youself, this WILL only make it worse.

Testimonial: "Im relieved to here that someone else is thinking the same thing. Im still going to try it myself as i am somewhat skilled at this but Thanks a bunch!"
2002 Mazda Protege5 with the FS2.0 Motor. The EGR Valve is located below
the throttle-body. You must take off the Intake tube to get a good view
of it. To replace it I think you might have to take off the

Good luck (remember rated this).
