    Any idea on what to do next?

    Hey all, I have a 1989 W150 with the 5.2. Sorry for the long post but here’s the whole story: Bought the truck from a “dealer”, ran fine for a couple months (driving into town a couple times, that’s all). It didn’t have much power so I figured I’d change the plugs, wires, and do an oil change...
