Attn: F250 Rob. Yeah, I know plenty of "techs" who are just parts changers too. Some guys, me included, like to work on their own stuff or maybe can't afford the dealership. There is nothing wrong with that. You getting on here and blowing off like a 7th grader about how much you know is uncalled for. If we want to know how to make our trucks run better, we can find out right here.
