So I'm trying to find a truck, and I came across a pretty good deal.....BUT I don't know shit about diesel's except for "regular mantaince and it'll be good" but I have read quite a bit about having to replace injectors on the Dmax which is between $3-5k and I dont want to buy a truck just to drop alot of money into it (I already have a project). Its and 03 with 85k miles, what are your opinions??
