Failed Emissions 200 1987

There's some some emissions info in the FAQ. Also check out this article for good background info: RWD - Real-World Repairs for Real-World NOX Failures

If you are able to adjust timing, I'd be inclined to check to ensure it's not overly-advanced.

Otherwise it could be the cat. I just took my Volvo through and 9ppm on NOx. No spiffy mods and regular octane gas.
