2004 6.0 surging issue
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?
Thanks for any advise...
