This can be done by attaching a regulator to your shop air hose; then attaching the hose to a vacuum fitting or the (PCV) valve fitting on the intake manifold; carburetor or throttle body.

Can you use WD40 to check for vacuum leaks?

A: Yes. You can use regular WD40 to detect vacuum leaks. The impact it has on the engine may not be as dramatic as carb cleaner or starting fluid, but it will still work.

Can vacuum leak cause low idle?

Such leaks, which go by the name of vacuum leaks, throw off the air-to-fuel ratio. Specifically, by allowing excess air into the system, vacuum leaks create a lean fuel scenario. As covered above, lean fuel can lead to misfires which in turn lead to rough idle.
