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.

the front spark plugs are easy just remove the coil packs and there right there, now the back ones are a bit tricky if u want to tackle it yourself, because you have to remove the intake manifold to access the coil packs to remove the sparkplugs, i also recommend remove the cowling and wipers this gives u more room and opens the area up to make the job simpler, when removing the intake manifold try not to damage any connectors you should be able to find a do it yourself book at a automotive store but if at any time you feel you do not have the skill to do it successfully stop and put it back together
