A stuck injector would sure do it.
Before proceeding, check the status of your insurance on the garage and its contents along with the location of fire extinguishers. Nothing like a little excess gasoline to raise your blood pressure 20 points and to remind you that fires are really bad things to have happen to nice cars. ((OK maybe I'm kidding about the insurance, but you do have a fire extingusher or two handy, right?))
Your engine won't like to drink that much gasoline. Pull the plugs and let the cylinders air out too. If you do have a cylinder full of gasoline, hand crank the motor to get most of it out. Also, be prepared to change your oil before running the engine, since fuel will seep past the rings and polute the oil pretty quickly.
Your next step to restoring the car to driving health is to remove the injectors from the intake and test fire them. If you are a parts junkie like me, you'd have enough spare hoses, fuel pumps, switches, etc to be able to rig up a spare fuel pump and run kerosene through it. Using it to flush the injectors and monitor the spray patterns is much safer than doing that with gasoline.
When ordering spare parts, be sure to get a full set of the large and small injector seals (one of each per injector). It's a good time to replace them.
