Rabbit flooding

My 1.6 VW Rabbit has been flooding like mad (may or may not have been
brought on by the colder weather, not really sure when it started
exactly). There is a very strong smell of gas fumes as soon as the car
starts but I do not see any leaks, I am pretty sure it is unburnt fuel
in the exhaust. The car also idles way too high (2000 RPM) and
adjusting the idle screw in the back of the throttle body has no effect.
Any ideas?

Do the injectors leak when you follow the injector testing procedure
in the Bentley manual? Do they have the correct pattern as illustrated
in the Bentley? Does the auxillary air regulator close as per the
testing procedure inthe Bentley manual? Does the fuel pressure follow
the pattern in the Bentley when testing the control pressure
regulator?

Just wanted to say thanks, I got the problem fixed. It was a
combination of a crappy injector (leaking) and a faulty air regulator.
