I FOUND AND FIXED THE PROBLEM!!!!:girl:
I was lookin around my whole engine and i found a little vacuum hose that was disconnected right underneath the power steering reservoir. I have no idea what it's for (considering there's like 600 vacuum lines), but i hooked it up, threw a zip-tie on it, and wahhh lahh!!
I still can't believe i spotted it, it was definitly hiding from me. I'll take a picture of it later today and show you guys what it was:biggrin2:
