Intake vacuum leaks

[jg61022]

Hi. Sorry if this question sounds stupid. How do you check for intake vacuum leaks?

[Crunkrich]

look at all the tubes that run off your intake and make sure all of them are secured in place with no leaks... there are 4 of them on the intake tube if you count the AIV hose. 5 if you count the resonator, which is right under the 45' bend after the throttle body

you check for intake vac leaks with the engine running and a can of carb/brake cleaner. when you spray the area in question, it'll get sucked in if there's a leak there.
