hello. My question is this, my toyota rav4, under the passenger side, there are 2 vacuum hoses that were disconnected, I noticed a hissing noise and I checked under the car and these 2 hoses were disconnected, I replugged them and the idle shifted speed. I want to know what these 2 hoses do and why there was so much oil aound that area. Thank you.
