my 2003 ford winstar

hey guys, I have a 2003 ford winstar that i need to get an emissions test done by tuesday.the 2 codes that i recieved said that 2 - (O2) sensors were bad. I think that it is just a vacume leak. how can i tell"? i heard that i could spray break cleaner spray around the suspected area to find it is that really true?

The most used tip I've heard is instead of using brake clean, you take an UNLIT just open propane torch to the suspect area (intake, manifold, vacuum hoses etc) and using the gas coming out of the torch listen for when the idle picks up. Some brake clean may damage your hoses.
