Yep, PCV valve is hidden under pass. intake manifold (plenum). I've heard people say they have removed it with a long needle nose pliers, but I sure couldn't. Had to unbolt the intake plenum. Look at the vacuum lines on the passenger side of the plenum. Look for a single connector with 3 little lines coming off of it. Directly BELOW this plug, there is a larger hose. That leads to the PCV valve. There is also a rubber grommet that fits into the valve cover that holds the PCV valve. This becomes hardened and brittle, and will crack when you remove the pcv. Mine was so hard that I had to use a pair of pliers and a good amount of force to pull the pcv from it. Replace this grommet while you replace the PCV valve. Buy a can of carb clean and clean the intake manifold, throttle body, and plenum while you have it all apart. Don't forget a new plenum gasket too.

Normal/Power button modifies shift points on your tranny, allowing the engine to rev higher before it shifts.
