The PVC is on top of the oil seperator. look down at your engine, under the right side of the exhaust manifold is a rubber hose that makes a 90 into the top of the oil seperator (which is nestled up to the crankcase). That hose attches to the PCV valve, which supposedly just pulls out. I've never even been able to get the darn hose off to try.

To clean the MAF, first unplug it and take it out, as in out of its housing. There are two torx screws that hold it to the housing (you don't have to take the intake apart). look into it, there are two wires, one mounted low and in front, the other mounted high and in the back. the back one tends to get really dirty cause thats the one in stagnation. use a cotton swab and some rubbing alcohol to clean them both. it really smooths the idle if its dirty.
