I wanted to post a follow up to my syndrome issues.

I changed the Temp2 sender, unplugged the O2 sensor and had soldered in a 35V 22uF capacitor.  I ended up getting surging while driving around town which had never happened before.  I can't get my O2 sensor out and a new one is sitting on the work bench.  I may have a little cat bypass pipe made with an O2 bung in it.

Peter Lapp driveway camped with us last weekend and was kind enough to give me one of the VW AFM pigtails.  I removed my capacitor and plugged in the pigtail.  So far, so good!  We'll see when I get it on the freeway this weekend.

Once again, thanks for all the help!

Just wanted to say that you guys are awesome. I had completely forgotten about how the O2 and Temp2 sensors play into this. I had the blinders on!

Let me do some work and get back to you guys!

I am no specialist in the vanagon syndrome but all the vanagon I own has
that problem..

as suggested the O2 sensor, the temp2 sensor, the throttle body switch all
can give the syndrome...

as for the AFM the things to do is cleaning the the carbon track, add the
capacitor or the pig tail harness. Another thing to check is the AFM
harness it self, it has to be in good condition and the cable is not too
tight...
