Water?

LOL, no.

CARB CLEANER.

Spray it around while the car is idling. If the idle surges, jumps up or it almost kills the car...then you've found your leak...follow the blower, LIM, TB, vac lines, fuel injectors, etc...all that crap.

And you have to unplug it, then remove the 3, 10mm bolts from the blower that hold it in...it is worlds easier with the supercharger off the car though...so, expect a few hours ****ing around.
