My 84 westy still has this intermittent cut-out problem although it
isn't as bad as it used to be.  It seems to happen mostly at low
throttle settings like 2200 rpm in third on a level road when it is just
keeping Smoky rolling along.

Sometimes it will cut out while idling - usually just as the light turns
green.  The problem is unpredictable.  Never know when it will happen
and have so far been unable to make it happen.

Maintenance so far:
replaced the fuel filter
replaced plugs
tested leads
checked distributor rotor and cap
replaced the ignition switch
had the engine cleaned
found and replaced a broken wire on the hall pickup
replaced a couple of suspicious hoses
very carefully adjusted the throttle switches
cleaned all the ground straps to the engine
swapped computers
replaced the air flow meter and tuned engine (C$750 8<O  )

What else could be causing this irritating problem?

TIA
