And for the water... Check your throttle body coolant lines for leakage.

I by-passed the throttlebody coolant lines years ago. Just use a metal or plastic connector to hook both hoses together. Then get a couple of large vacuum caps and put onto the TB fittings (looks better, and keeps dirt out).

I recommend doing this to everyone. The ONLY reason coolant is run thru the TB is to warm it up sooner for a little more emmisions control. BUT......The cooler the air going into the engine, the better it runs, and more HPs.
