It was a long story. I was almost a year behind in inspections. Didn't know until getting a ticket. Getting consistent high NOx. Replaced complete exhaust w/ after market cat and new O2 sensor. Didn't help much. I posted the problem a few months ago.

Have been travelling a lot. No time to take care of it until now. It has been sitting on our driveway. Two weeks ago our daughter drove it to Newark Airport to pick us up. She got another ticket for the expired sticker (failing to make repair). Ouch!

Removed the flame trap yesterday. It was not clogged. But I will clean it. I loosened the intake manifold, just to make sure it doesn't have EGR because I couldn't find it.
