Yeah, I'm referring to the air-cooled vans.  You have a point, maybe
there's something that needs to be done periodically to the EGR circuit.
I wouldn't know, some PO helpfully destroyed the EGR stuff on my van
through the not-particularly-clever strategy of wrenching the linkage
out of the throttle valve and leaving it bent beyond repair and hanging
in clear view (grrr), leading to yearly 'discussions' with the emission folk.

I had been thinking of the California air-cooled vans, which have an
oxygen sensor.  The federal (non-California) vans didn't.
