So last night I was out and about and around town in my 86 Westyand got
home at 10:30 pm and parked the van overnight.  The van was running well -
no symptoms no concerns.

This morning I had made arrangements with my wife to take the kids to day
camp so she could head to work a little earlier.  Anyway we all piled into
the van to head out to camp and the van would start right up but would not
idle or run at all - not unless I had my foot on the gas pedal.  Very
perplexing....how can a vehicle be running really well 8 hours beforehand
and not idling the next day?

Luckily my wife hadn't left so she took the girls to camp and I walked to
work thinking about possible issues.

Fast forward to about 15 minutes ago - I grabbed a beer and decided to
start looking at the engine compartment for anything obvious - hoping that
my limited mechanical skills would detect something.  As I scanned over the
idle stabilizer and throttle housing - something caught my eye - the idle
adjusting screw was missing and there was an air entry hole in the housing
where the screw should have been.  I looked below the housing and saw the
screw - very lucky!  I screwed it back in and found a place that seems to
work for now - until I take the van to my mechanic to properly set the
adjustment.  Just took it for a quick test and everything seems to be back
to relative normalcy.

I wonder how often this occurs? Anyway I thought I'd share the experience
as another one of those things to check.
