I know this question has been asked, did a search and could not find it. I have a 2007 2500 6.7 diesel and just replaced the EGR valve. About a month later the engine light comes back on. Any ideas I read a some threads saying the o2 sensors get soot on them which causes that light to come on all the time. Any recommendations would be helpful. Thx Don
