Re: 2000 6.0L runs rough and stumbles

my buddy had a lot of the same issues with his HD. we ended up changing the plugs and wires, and the knock sensors. all better. turns out the plug wires were breaking down and not putting out enough juice. the engine has two knock sensors under the intake plenium. one of which was broke of (looked rusted in two) and while we were in there we changed the other as well for added insurance. not saying thats ur prob. but if you could analize live sensor data, you could see it maybe as stated before
