Your intake plenum(big gray thing) has 6 bolts. 2 in the front 2 under the plenum cover(thing that says 5.0) and 2 in the back. locate the 2 in the font and on the exact opposite side in the back you will see the other two bolts. Just behind it you will see it. there will be a bunch of hoses follow the biggest hose and just pull it. it should come right off from PVC valve. to replace it I suggest removing the hood and using a pair of pliers to pull it from the grommet. if you can hear it rattle its good. you may also want to replace the crankcase filter if its clogged. use pliers and a long screw to remove it.
