Finding vacuum leaks...???

I remember hearing a really good way(simple) to find vacuum leaks but can't remember what it was. Anyone know what it was? (I'm working on a 91 Ranger that seems to have a vacuum leak but can't find it.)

You can use a propane torch (without the flame) to throw some enrichment gas at specific suspect locations. To get the most fuel gas to the location you want try blocking the air intake ports on the torch. When you direct gas at the leak the engine will change rpm. Use only in a well ventilated area and watch for open flames. Careful!!!

Actually what I found was to take that propane bottle, unscrew the flared fitting with the little holes, add a length of rubber hose of the small diameter and a one of those vacuum line splice connector (small orifice...then youve got better direction and concentrated flow...And last but not least, remember propane is lighter than air so start at the top and work your way down...
....Or ya could just go buy a can of carb cleaner....

wabiker,
propane is heavier than air.
i usually dont nit-pick other's posts, but this is a safety issue.
I hauled bulk propane for 4yrs, and have seen my friends lose eyebrows, get burned, and been thrown 20ft by an explosion.
luckily nothing serious has happened to me, i just got freeze burned once. liquid propane is -43 degrees F, and if you get in contact with it, will actually"burn"you by freezing your skin.
respectfully yours,
eden
