P0672
Just got my new to me truck and it's giving me a code P0672 which I understand is glow plug #2 or harness. My question is will it hurt anything to run it like this until I can find time to repair it?

Nope. Just have to tolerate the Check Engine light until it is repaired. The good news is cylinder #2 glow plug is the easiest of them all to access on this engine, so if you find the motivation or time to get to it, it's just a matter pulling the glow plug itself out, and checking the resistance. It should be between 0 to 2 ohms. Any higher than that, mandates replacement.
