Mike, You previously mentioned cleaning the IAC valve: the screen is cleaned how? It doesn't seem possible to remove the screen and blow out gunk from the inside of the screen, but blowing gunk in past the screen into the valve seems to defeat the purpose of the screen. Do you use a type of electronic connection cleaner or something like brake-parts cleaner? Does the IAC valve work like a piston which might benefit from light lubrication inside the valve opening? Sure appreciate your comments on maintaining the IAC valve in good working order as it is very expensive to replace. Stan
