SOURCE: Fuel Injectors leaking
Where the injector's mount to the fuel rail and into the eng. there are o-ring's.Check the o-ring's for damage.If the o-ring that seal's the inj. to the fuel rail is damaged it will leak alot from the pressure of the pump and make the car act like it's running on 3 cylinders because there is no fuel going to the cylinder to ignite.If there is a bad seal in the area where the inj. goes into the cyl.head it will leak a little and should be fixed as well.When installing new o-ring's lube them up litely for a easier install.Be sure to clean the gas up so you dont ignite any spilled gas.Hope this help's.

Just spitballing here but sounds like contaminated fuel or a block in the fuel line and or pump. Here's a link with a diagram for locating and checking the fuel line and best of luck to you.

Yes, could be any number of things. It could be the TPS (throttle posistion sensor) as this is the culprit of most idle issues with fuel injected vehicles.
