Vacuum leak, lets try this again
ok, so I am almost 100% sure I have a vacuum leak. I did the test where you cover the TB to see if the motor will die, but mine seems to run just fine, the idle drops just a little. I don't have a diagram for the vacuum lines since I have a CF hood, and a mini-me with a d16y7block, d16y8 head, d16z6 Intake mani with an LS TB. Where would I start looking for these hoses?

you should get some carb cleaner, and with the engine running, spray it all around the intake manifold. if your engine idles differently when you spray it, thats where the vaccum leak is.

I sprayed it around the mani, and nothing happened. I can't get it under the manifold though :S.

Make sure the throttle body gasket your using matches up with manifold, can leak on bottom side of TB. Seen this happen, spray carb cleaner up from under the car!
