Hey Neil,

I had all my tools available and let the car sit for a couple of days, then warmed it up and experienced the full stall effect. There are two small solenoids that activate what looks like valves to vacuum tubes. These are on the passenger fender and click when the engine dies. Not sure if they are related at all to the charcoal canister you mention. I disconnected the wires to these solenoids and found it makes no difference. I have the unfriendly service CD and will try to look up how fuel vapor system works.

Robert
