Look at the rubber caps that are supposed to be on the intake manifold. There is usually one on the back of the manifold. Otherwise the intake gasket itself, possible a leak around your injectors. All kinds of options.

is your crankcase breather plugged into the intake? Thats where I was leaking from.

hmm, i did have a problem with fuel leaking from my injectors when i put them on... but from what i can see, i dont see/smell and fuel from that area... ill go around my motor and check for any missing plugs or loose hoses.

its the idle, as long as it runs and doesnt pop, just let it be lean

A smooth idle that doesn't fluctuate is worth looking for a vac leak.

damnit...my idle will do that too...sometimes...and everytime i drive the car and put it back from neutral it will drop pretty fast and bounce at the 0 and come back up and paly a little bit and go back to normal. I KNOW i don't have a leak. redid all my selicone vacumme hoes and took it to my friends smog shop and smoke it for leak. no leak.....i think its a matter of tuning... making it idle right.
