it's all about the heat. Even with a working EGR, the heat builds during extended idle. It's heat that creates NOx in the first place.

once the cats start to overheat, all bets are off.

Even a three way cat, like those on my 92, won't kill NOx without the help of a working EGR... or, a cam with appropriate overlap.

Andy.. They don't even put EGRs on cars now. Newer cars are more fuel efficient, make more power, have less emissions without an EGR or a smog pump.

While the EGR does help on older cars, the L98 had a crap tune from the factory and I'd think a new cat and better tune would result in better emissions.
