The following is as much as I know. Somoene else continue.
STEP 1. Remore air intake manafold and block with hand
a) if car stalls (stops) == No leak likely
b) if car continues to run == leak definite
... any text and general diagrams of vacuum lines in 97 acura integra LS will help
You just want to disconnect the intake tube from the throttle body. Any hose that connects directly to the intake manifold is a vacuum hose. The method you speak of will work to an extent.
If you are positive there is a leak somewhere, you can spray Throttle Body or Carb cleaner around the IM and look for bubbles.
