Line Dodge

What is the purpose of a line of PVC in a Dodge Caravan?
Recently I had changed my line of PVC in my car I think it was not properly installed. Since then, my car turns suddenly while driving. Would a loose line PVC fault?
I think you mean the PCV valve, it draws only vapor and gases from the engine and again to burn in the combustion chamber, but if it is right not to bulk or a vacuum leak and the idle speed is higher, will be looking id or moving Lines or anything to be with emissions, it could take to the masses, a different line when you install the PCV valve or left something loose on him, That Sound not like a bad PCV valve is good luck.
