so far i've been using the pressure-test + soap water method.

i read about another method where a combustable gas is sprayed around suspected areas while the car is idling (with IAC unplugged). as far as the spray i've read "carb cleaner" & "brakleen". i thought seafoam spray may also be used.

it seems somewhat easier. any opinions? risks? cons?
any sprays not to use? any ingridients to watch out for?
any recommended sprays?

Smoke test would help.

I saw a propane bottle being used once. It uses a small amount and changes the idle.

those machine only produce 1.5 psi....kinda sucks IMHO

was able to find a leak with a smoke test when I first got the car, but it was a rather large one.

smoke testing seems safe; but i do not have a smoke machine, and it seems similar to pressure-testing which i have equipment for.

propane seems risky. i dont think i'd like to try that.

told us before...spray it around, when the idle increases, you've found the spot...just be careful not to start ur car on fire...I would have a fire extinguisher handy just in case...

That won't work in all scenarios. Some leaks require lots of positive pressure to manifest themselv
