Well if its anything like the 2000 3.3L Pathfinder (which I can't guarentee it is, but its worth checking), there are two hoses coming out the engine block on the right side (driver's side) Pull the hose out thats closer to the windsheild (if it helps the area is called the upper intake manifold) Its threaded in that hole where the hose attaches.
I'm doing this tomorrow, i'll take and post pics. Hopefully it'll help.
