rough-idling engine can signal a number of positive crankcase ventilation (PCV) valve problems, such as a clogged valve or a plugged hose. But before beginning the functional checks, double check the PCV valve part number to make certain the correct valve is installed. If the correct valve is being used, continue by disconnecting the PCV valve from the valve cover, intake manifold, or hose. Start the engine and let it run at idle. If the PCV valve is not clogged, a hissing is heard as air passes through the valve. Place a finger over the end of the valve to check for vacuum.
With the engine at idle, vacuum should be felt at the PCV valve.

I suggest to get the codes checked so you're not chasing a moving target. You'll need to look online - check out the Ranger/Explorer forums - or get the Factory Service Manual (FSM) to get the technical info you're requesting.
