EGR valve with vacuum applied kills the motor at idle = works
Egr modulator applies vacuum to egr valve at 3500 rpm = work

I go for smog again tomorrow. I've tested everything but the cat. Universal Cats were cheap on Rock Auto.

I'm moving to CA. Believe me; I'd love to keep it in NV but it's not realistic.

The new O2 sensor helped improve power a lot. More power down low and all the way to 4500 rpm. (at least for the van)

I blew out all ports. The a hard line running to the BVSV was clogged.

I found out today in CA classic cars are only pre '75.
