Misfire
3rd Gen, I love the truck. It went into limp mode, I had the turbo checked, and it’s good. Put a new waste gate actuator and solenoid on it. I changed the air temp sensor, manifold presser sensor. It had a code 2146. I ohmed out fuel injectors and found a bad one, I changed it and the harness and fuel filter. It ran good for about 5 minutes and then it threw codes 300, 304 and 306. Which is misfires in cylinders 4&6. What else can it be? What have I not looked at? I need my truck! Any help will be appreciated.

hey thanks, i found it,
I got home and it was still knocking, i did not think it was valve adjustment cause i did not touch it and it ran fine before. So I took off the valve cover and started it and then took a wire off of the injector i just replaced. Go figure the knock stopped.
so I got a bad one.
going to call them up today and have them send me another one.
thanks again

melted piston. Common on trucks that lose a injector and run for a while without knowing it. Put a camera down the hole just for piece of mind! Rare that a new injector is bad but possible! I'm just guessing without actually seeing it! Valve seat still comes to mind but depends on the year early models 03 04 more likely.
