I currently dont have the resources or money to fix the knock sensor or the engine coolant temp sensor, anyone know just how serious these issues can be if left unmaintanenced for about a month? I'm kind of a dum dum with mechanical stuff, I've been trying to learn with these forums, google and my chilton manual but sometimes it feels like I just cant figure it out.

 

Your main problem will be that the truck will run like crap (code 52 results in very retarded timing, code 22 will interfere with the shifting of the automatic as well as other issues). But other than slowly fouling the plugs, you can probably get away with driving for a month. Much more than that: all bets are off.
