question 2, i recentlty put a new k&n on my contour and it worked fine for like 3 weeks, and now i started it up today and its making a strange hissing sound, its constantly sucking air in like it would when you would accelerate.

The hissing sounds like a vacuum leak as if a vacuum line has fallen off, IMO. Look around under the hood and you'll probably find a disconnected or cracked vacuum line.
