Many thanks to all of you, esp Kenneth D Lewis, as it was his suggestion
of unplugging the O2 sensor that isolated my problem.  I was having the
problem this morning, and unplugged the O2 sensor, and it all cleared up,
now my question is, where from here?  I know the O2 sensor is good, will
it hurt the van for me to drive 300 miles back to school today with the
sensor unplugged the whole way?  What should the "real" fix for this
problem be?  What are the chances of this leaving me stranded along my
drive back to school?  Thank you all very much, I am leaving in about 2
hours (1:30 PST) so any quick informed responses are greatly valued.  Yau
guys are sooo great, thanks again....
