In my experience, >90% of idle problems relate to vacuum leaks.

Easy to check for with carb cleaner spray; spray around the various
hoses, fittings etc with motor trying to idle. When you hit the leak,
the timbre of the motor will change.

Subject: 87 westy will not idle

Hi all,

     Had a interesting problem this morning.  I went out to start my bus
about 4:30am & the bus would start but die as soon as I let off the gas.
I tried this about 5 times but could not get it to idle.  Finally took
another car too work.  The bus drove fine all yesterday.  Drove about 60
miles all day with no problems.  Anybody got any ideas where to start?
I replaced the idle control unit about a month ago.  Could this have
gone bad?  TIA.
