Is there any way to know if these actuators are starting to go bad? What do these actuators really do (sorry I am pretty noob to how internals of an engine work)? I have near 60k miles on my car and my car idles like I need a minor valve adjustment. I probably should have checked these out prior to installing the supercharger.
