My Sammie does a strange thing when I shut it off. If the heater fan is off, it shuts down like a normal vehicle. But if the fan is on high, like it is all winter, the engine will run on until the blower motor slows down, which can be around 2 seconds. It is not dieseling, it just delays shutting down while the blower motor is turning. My theory is that the blower motor is generating power as it spools down, and that is enough power to keep the ignition system going for a second or two. But is seems like the blower circuit should be divorced from the ignition circuit. Anybody have similar behavior from their carbed sammies?
