Hello, Scotty: Hey, I enjoy your humor and delivery as much as the tips and information you provide. It is like having Jay Leno for both a buddy and a mechanic. Anyway, I just picked up a Honda Odyssey with 113K, a V6. The engine races up and down between 1K and 2K RPM. The seller said it is a common Honda problem with the "Idle Control Valve." What is your opinion and can I fix it myself. With four cars I need to save bucks, especially that one of mine is one that you are not fond of, a Mercedes-Benz S430. Your new consolidation with the other experts is fantastic. Hell, run for President and I will vote for you.
