Now that I'm a Dodge owner for the first time, I've got some concerns about this truck. With only having it for a couple months, I've already put about $500 into it just to be able to drive it. I've got to put more into it with having to replace the plenum gasket. And now I've noticed that when I put it in gear it makes a strange sound. Do I keep dumping money into it or get rid of it?
