Any advice from you fellow listees on this would be appreciated TIA

My 85 Westy with Digijet has the following problem; After driving at 60-65 for
awhile and then coming to a stop (clutch in) the engine dies. Or if rather than
coming to a stop, slow down to say 20'ish the engine surges from 1200 to 1600
RPM (which causes the van to buck badly). If while surging I simply push in
the clutch and stop/restart the engine the surging goes away. Sooo any ideas???

I assume what is happening is that the ECU still thinks its at highway speed
even after I slow down. This would explain why restarting the engine while
rolling along clears the problem (the ECU gets reset). TIA for any ideas!!!
