Thanks again for the info !
he is correct ! the very first signs of a lean HSN is hanging idle after a WOT pass.....Usually it happens when you are only slightly lean, you have enough fuel for full power, but not enough to idle down correctly..............Also too much idle gap can cause that, and so can a lean LSN.....
