The 80 passed emissions today. I was expecting it not to because I keep getting intermittent P0401 (EGR) codes.

My numbers were:

HC GPM Reading 0.0576 Limit 1.2000
CO GPM Reading 1.5318 Limit 15.0000
CO2 GPM Reading 549.5035 No Limit
NOx GPM Reading 0.4276 Limit 3.0000

So why am getting this P0401? It goes away after a while, too, and then comes back! I'd kind of like to fix it so the annoying light doesn't keep reappearing.

The plugs are fairly recently new. The engine is a little dusty still from Moab. I haven't checked the air cleaner yet. What else should I look at?

Take it to Ben and have him fix it...That's what I did :)

Now I have another code, P0171 I think, but only when the truck idles for awhile...Still trying to get that one tracked down.

Congrats on passing emissions!! Seems pretty rare anymore for an 80 to pass first time...

There should be a club or award for 80s that pass on the first time through. I just failed twice in a row and with the condition of my rig I've got my work cut out for me! I'm going to see how much I can get done Sunday and go back on Monday morning and see how the pig does.
Congrats and cross your fingers for me!
