Look at your air intake manifold. On the top of it you will see a vacuum port with two or three vacuum lines going to it. Directly behind it about three inches is the EGR valve bolted to the manifold.
Another possibility is a bad catalytic converter. I had a Ford truck that wouldn't pass and it turned out the guts of the cat converter had blown out and clogged the muffler.
Is New Mexico doing SMOG checks now? We lived in Socorro a couple years ago and didn't need one.
I'm curious how someone could determine how much longer your EGR valve would last. He must be some mech. I have a '93 1.9L and it has the original. All I've changed is the Oxygen Sensor and PCV valve.
Let us know what you find out. Watch out for the Bosque Fires!
