Have you checked the throttle body gasket? There a few vacuum lines up there.

how do you know you have a leak at the throttle body? are you sure your not hearing the bearings in the alternator?

i did the brake cleaner trick. and it came from under the throttle body. i replaced a cracked hose running from the intake manifold under the throttle body to the pcv valve. also replaced the throttle body gasket and cleaned the throttle body. but still no luck

you spray brake cleaner or starting fluid around the area you think you might have a leak and i will cause the the rpm to either drop or go up.
