A faulty PCV valve can certainly cause idling problems, especially after the engine has warmed.
Have your cold air intake checked out.
My car idles really high and wont go down and it will stall if I push on the gas!!
There must be a "check engine" light on. Start with investigating the DTC's (Diagnostic Trouble Codes).
The spark plug gap can cause the RPMs to fluctuate, while idling. The more probable cause of the fluctuating RPMs is a bad camshaft.
When you are shifting gears, your RPMs will go down because your clutch is being pressed. If your RPMs don't go back up when you release your clutch, you should see a mechanic.

UV light cause cancer. It is because it can penetrate deep down into the skin.
I had the same problem. It would stall out after coasting down a hill. Cleaned the throttle body about six months ago. Has not stalled since then.
