My 84 has completely sporadic problem.  It shuts off going down the road.
It usually kicks back in before I have to pull over.  It happens cold or hot.
I have the idle stabilizer bypassed.  If I connect the idle stabilizer the 84 will
almost always stop and not want to start again.  I can always get it started 
again it just takes about 15 minutes of waiting in the worst case.
I have cleaned up the grounds I could find.  I saw a post to change the temp II
sensor.  I have one on order now.  I changed the plastic part of the ignition switch.
I checked the adjustment of the throttle switches.  I swapped out the ECU with a 
known good ECU.  Thanks to VanAgain, Bus Depot and Rocky Mountain.  I have 
the bentley CD and finally figured out to print the pages "as they appear" in the 
printer options.  Any idea's?
