2004 6.0 surging

[axe124]

Looking for some help...I have a 2004 250 CC/SB. I've only owned this truck for about 8 months. When I first got it had about 76000 miles on it, now it has 83000. Occasionally it would do (what I call) a surging when coming to a stop and or idle. After reading numerous threads on here, I was pointed at the EGR. So I cleaned the EGR and replaced it. Finally, the surging was gone...until last week, the dreaded surging returned.

I know this may sound crazy, but I feel that I have narrowed down the surging to when it rains?? Last week in the rain it began surging, dried out for a few days, surging gone. It rains today...surging back. Although I really don't want to take it to the dealer just to hear him say...cannot duplicate the problem, therefore no fix. Any ideas of what I could try, point in the direction of, etc?

With that being said, does anyone know a local shop?? I don't want to go to far, but I need someone that knows what they doing.

Thanks for any advise...

Still sounds like EGR..it may be a coincidence with the rain. Your EGR cooler may be junked. You can uplug your egr on the top of the EGR filter there is a electrical plug. Take out the plug and run around to see if this helps. Are you getting any smoke, like blue or white?

Thanks to everyone that replied and tried to help me out. Took the truck to the dealer today and after they checked it out, they said that they needed to replace my ICP Sensor, and EGR.

Hopefully this has fixed my issue. I have only been able to drive it for a short time tonight. Time will tell.
