Can I Ignore This Error Code (97 Mazda 626 Filter)

The car my son drives (97 Mazda 626 with the 6 cylinder engine) is throwing a P1195 OBDII code. That is a error reading from the EGR sensor, but there are a variety of things that could cause that, and Google didn't turn up any advice about whether or not that is really a critical issue to deal with.

He said it was idling rough, but it was fine when I checked it yesterday. The car has 196,000 miles on the original engine and transmission, and I bought it in 2000. His sister is headed out of state to college in August and my goal with the Mazda is to get it through the summer because I think I'm going to get rid of it then as we'll have an extra vehicle while my daughter is away at school.
Of the most likely causes (bad sensor, clogged intake port, carbon build up) none of them seem to me to be things that are likely to strand my son on the side of the road with a dead vehicle. If I'm wrong about that please correct me. Also, emissions inspections are not an issue where I live.
What's the worst case scenario involving this code? The only other current ODBII code on the car is P0147 (I think.) It's an O2 sensor on the exhaust which has never had any impact that I can see on the operation of the vehicle. That code has been on for several years.
(Possibly related - he had a blinking CEL last week indicating a misfire on cylinder 4. The plug wires looked fine, so I replaced that spark plug and the code cleared and it's been fine since.)
