1999 Honda Accord ex coupe V6 (California) engine stalls immediately when blinker/signal lever is used, for left or right turn signal. When engine stalls, green "key" light flashes on dashboard. Otherwise, failure happens randomly. Failure has occurred both while driving at 60+ mph and while vehicle is stopped. At high speeds, engine stalls and then restarts in a few seconds. Has not occurred when engine was cold/not-warmed-up. Failure occurred about once a month at first, but in the last three months, averages about one failure a week. Failure started happening at around 70,000 miles. Car now has ~92,000 miles. Car has had one owner since purchased new. Car recieves regular scheduled maintenance. Car had complete tune-up (oil/filter, spark plugs, ignition cap & rotor, ignition wires, transmission fluid (Honda), air filter, fuel system cleaner, etc...) after first failure. Alternator failed and was replaced many months after "stalling/blinker" failures first occurred, and had no apparent affect on stalling problem. Stalling still occurs, and have no idea what cause is.
