i believe only the obd2 engines came with egr systems. it's a way to reduce nox without relying on the cat so much to do so.

i would do the maintenance stuff first, then retest and see how it fares. it's rather close. a seafoam and a roadblast should also be beneficial.

good luck with it and let us know how you fared.
