Thanks all with your good suggestions,
I was able to thaw the van out in my garage today and fix the problem.
I just traced all electrical connection around the sensors and ground wires and cleaned everything up nice and shinny.  I tightened every connection up. I found a corroded ground connection on the head.  I also replaced the distributor cap and rotor with new spare parts and changed the oil.
Unfortunately I noticed some blue droplets from the head gasket right above the oil pressure sender.  Damn! it was too good to last.  I did turn 90,000 miles this week.  Right on schedule. drip drip drip.
Thanks again,
Joel

Here it goes.
A few weeks ago I posted a request for help with MY vanagon syndrome.
Gasping for air and guzzling gas without any power!
I'm at the end of replacing stuff on this engine.
I have replaced the Temp II sensor (first culprit). Swapped the Temp I and AFM (second guess) . New air filter - all clean and dry. Checked the O2 sensor - All Ok per digitool. Catalytic converter is empty so no blockage.
Finally I swapped out the Idle Stabilizer valve. < This really solved the problem, sort of...
The van runs much better with the new (used) stabilizer valve. BUT, once the van is warming up I still get hesitations and loss of power plus spitting and coughing.
When the van finally gets to normal operating temp and it runs OK but could be smoother.
Help! I don't know where to look or what else to change, and I'm done cussing.
Any help will be greatly appreciated and should go down the Anals of Vanagonology.
Thanks all,
