Ok, you're right. I'm a novice but I had a funny feeling that saying it's a V6 was not right....
Anyway. the air pump? Does that mean that it should not be operating the way it is? That noisy? Like I said, it goes away right away, but is kind of embarassing as I drive out of my driveway in the morning.
As for item 2, I have already replaced the cylinder head, valve stems, valve cover gasket, new spark plugs, radiator, cooling system sensors and a variety of other items (radiator, for one). Could it not be the ignition wire set/harness?
