I was on my way home today and my check engine light came on and my truck couldnt go faster than 60 on the interstate. .. I have a 2006 dodge 4x4 cummins. Any ways I drove it like a turtle all the way to a shop and the guy said the code read p0299. The auto guy cleared the check engine light and so far it ran back home fine just dnt knw what I can do? Plz help

 

Well start by searching for what that code means...have you?
