There is a humming-type noise coming from the throttle body. Almost sounds like a mini-fan. I can't figure out what the noise is. I thought it was an IAC valve because the car idled poorly. I replaced the valve and the car idles perfectly but the humming, fan noise is still there.
On a side note, what is the metal hose that is connected from my air hose (that goes from my air box to my air filter) to the engine/exhaust beneath? I'm trying to learn the names for all these parts but there are too many! Anyways, that is really loose and I think I need to get a new one.
Also, there is a thud everytime I start to accelerate. Somebody has suggested that the exhaust may be missing a hanger? I just want to verify that it's a simple fix and not my transmission or something.
