I would say it’s definitely flooding except I didn’t think fuel-injected engines did that.
See? This is me, baffled.
*tagline*
Almost sounds like a bad ballast resistor.
Throttle body FI could and in some models did do that.
Throttle body FI is more or less a glorified carburetor with an electronic dodad that spritzes the fuel into the throat instead of a carb's metering jets.. If the electronic dodad sticks or whatever happens to it, it will allow fuel to drip into the manifold after the car is shut off. On the next starting attempt, it's flooded.. As I said, had a company issued vehicle that did that.
Now - does anyone know if that Geo has throttle body FI or port FI?
