Rough Idle
I have a new issue will my 03 Chevy 6.0. When the truck is cold it idles rough. Doesn't actually feel like a misfiring cylinder. In gear at a stop light the idle will drop below 500 rpm and the engine...

I had my old one do the same. Intake manifold gaskets were leaking. After I fixed that issue I had the Cpk go out.... that was a easy fix as well! That 6.0 is so built proof that I bought an 09.. my old one had over 200k. So that's my take on it, replace the gaskets with the newer updated ones. Good luck and keep us posted.
