I have a 99 k3500 5.7 v8 dually and the truck runs great everything is good on it. It idles fine, drives fine, everything. Only code I have is o2 scensor on bank 1. I had the p1345 but fixed it the past weekend in hopes it would fix my issue too. It only happens when it warms up and only when I'm in drive or reverse and hold the brakes to stop. Please just need to know where to start looking to fix this annoying issue. Tired of having to put my truck in neutral at lights.
