So I’ve had my truck for a few years now and I’ve recently gotten more interested in it. I’m looking to make it run better than the average 3.9 v6, so far I’ve only done the basics like ignition wires, oil change, and air filter change. I literally have no clue what to do next to make it run better because I don’t know much about trucks. This is gonna be like my introduction into working on vehicles. So if anybody has any ideas or can tell me what would be good ideas or good parts to add or replace that would be great.
