For finding air inlet leaks the easiest way is to just gently squirt some WD40 or Carb cleaner around each nylon or rubber vacuum hose or joint when idling....when you have a leak the revs of the engine will rise.....also bend gently the 90 degree rubber bends to see if they have perished or not.
One of the main places for leaks or splits is on the EVAP canister the hoses on the top tend to split if old.
Also check the nylon vacuum hose under the fuel rail for the FPR make sure it is clear of obstruction by blowing through it when disconnected.
