 Note: gap on plugs should be 0.040" Sorry about the typo...
I'd start with the basics since they are cheap: (1) New properly gapped> 0.40" OEM spark plugs, (2) New ignition wires if these are more than a> couple years old (make sure they are routed properly), and 3) a good fuel> injector cleaner (e.g. Techron).

 The mileage helps, but you do not indicate when the plugs were last replaced
or the wires. My guess is that you will also definitely need to remove and
at the minimum clean (worst case replace) the EGR valve.

As background, my son's '96 Saturn 1.9L had 115K miles when the EGR failed.
When I removed it it was pretty coked up in the passageway and was
definitely sticking. I used a small flat blade screwdriver to chip most of
the stuff out and then used a small dermal tool with a wire brush attachment
to polish up inside there as best I could. When I was done I used some
throttle body cleaner to dissolve whatever else might have been in there.
When I was done I cleaned the passage ways to the intake and exhaust
manifolds with a small "battery" type wire brush (for cleaning inside the
battery clamp). The EGR valve operated manually beautifully when I was done
and everything was pretty clean. The new gasket cost us about $3 and when
we put it all back together it worked fine and the code (different from
yours, but my guess is your EGR is so bad it won't operate at all any more)
disappeared.

My point here is the EGR is pretty simple to remove and may be reusable. He
has subsequently driven the car for about 1 1/2 years without this
re-occurring.

My last thought here is if it has not been done lately, replace the PCV
valve since these have a tendency to clog and can cause oil burning which
can cause spark plug fouling and accelerate the EGR problem.

Good luck. Most everything I've suggested here is low cost and easy to do
yourself.

Bob

PS The fuel and air filters are other things which should be changed
regularly. The air filter is a breeze to change, but the fuel filter can be
difficult due to its location.
