what is the Vacume Leak test procedure

[dohc122acr]

How do you find a vacume leak? Ive checked all the vac lines I can see. Ive pulled the injectors out and map and reinstalled them. Can you check for a vac leak like you do a boost leak?


I'm only reading 15 at an idle and 19-20 on decel even from a high rpm down hill. Ive got stage 2 and it hardly pops on the decel. If I pump the brake a little I can get it up to about 10 and the things idling pretty high.

I've used carb/choke cleaner and spray it in the areas of possible leaks while the car is running. If the idle races for a second, you've found your leak. Spray around the intake manifold gasket, the throttle body gasket, and I've done around the vacuum hoses too. Good luck man.
