Good morning, My 2008 dodge ram kicked in the CEL last night, nothing abnormal had been done to the truck, we JUST did a dealer Oil change and now all of a sudden it's having problems. what i did notice is ever so slightly, the truck kinda surges at cruising speed. like it has sudden boosts of maybe 1-2 hp. it has about 73000 KM's on the clock, 4.7L V-8 (one of the new ones). If someone could tell me how to pull the codes on it manually, that would help me, nobody around here does it for free and my scanner only goes to '04. any ideas would be VERY appreciated, because it's my daily driver!
