hey, heres what you should do:
get a friend or whoever to start the car, get a can of carb clean with the red needle sprayer.
start at the throttle body, work your way around all the vaccum lines and eventually back to the iacv. wherever it starts to pick up idle is where theres a leak. also, tee into one of your vaccum lines with a boost/vaccum guage, you should have 20 (or close to it) on the vaccum side. if theres a significant loss of vaccum then you have a leak somewhere. also, test your bov like they were saying above and make sure you have a straight 8 or more inches BEHIND your maf, they tend to not like bends.
