Touched on this in another thread earlier. Anyone know of a test procedure for the XKR airbox valve underneath the
air filter? I bought a Jag service manual downloadable on eBay and while it is lengthy and covers a lot of the basics I could not find a test for this referenced. Searched the forum as well. There are a few mentions of this system but no way to do a functional test. Revving the engine to high RPM in Park does not seem to be the way to go about it. I am a total electrical boob so any electrical tests need to be explained as if you are talking to a 6th grader.
Thanks for any replies.
