problems with an 06 6.0
I bought this truck last year with no problems. Last month I hit 2 deer with minimal damage but required front end work. When I picked up my truck the first time the check engine light was on and stayed on for about 4 days and went out for about a week, then came back on for about another 4 days and goes out. This has been going on for about a month. I've had several different code readers on it and they all say something different. I've pulled the EGR valve and it was not dirty or wet. any suggestions???
