For anyone who has read any of my threads begging for help, I have found the answer.
After all the stuff I have done for routine maintenance, and to still have a low idle and rumble, I finally took the truck to the dealer.
They did an ECM UPDATE that solved every issue I have complained about. They told me that there has been a TSB about an ECM update after plug replacement.
My truck (2007) now idles at smooth, beautiful rpm of 800-875. No knock, rumble or anything else and was done for FREE because of the TSB.
I love my truck !!!!!!
