You don't have to go to Autozone, you just have to do the key on/off 3 times and then leave it at run, the codes are displayed in the EVIC panel at the bottom of the Tach. People refer to it as the "Key Dance", you can find youtube videos showing you how to do it.
Injector # 1 Control Circuit
An open or shorted condition detected in control circuit for Injector # 1 or the INJ 1 injector bank.
Injector # 2 Control Circuit
An open or shorted condition detected in control circuit for Injector # 2 or the INJ 2 injector bank.
Injector # 4 Control Circuit
Injector # 4 or INJ 4 injector bank output driver stage does not respond properly to the control signal.
Injector # 5 Control Circuit
Injector # 5 output driver stage does not respond properly to the control signal.
Random/Multiple Cylinder Misfire Detected
Misfire detected in multiple Cylinders.
Other vehicles I've owned, I had the wire bundle to the injectors chaff against the side of the engine and chaff through the wire insulation and cause a short. But that short to the injectors was associated with engine motion, i.e. it would run fine until I revved the engine or did something to make the engine torque in its mounts and suddenly I would have rough running and mis-fires.
Your's is associated with temperature, makes me guess you have dirty injectors, a can of injector cleaner in the gas tank can't hurt, add it before adding some gas to the tank, to mix the cleaner in the gas. The Chevron Injector Cleaner or Lucas Injector Cleaner seems to work the best, a lot of the cheaper other brands don't seem to do anything.
Although dirty injectors can cause some of those codes and the mis-fires, I don't see how they can cause the open/short circuit codes. Perhaps if the injector was dirty enough, and it sticks, that might be seen as a open circuit to the PCM, but it is possible you have injectors going bad or something wrong with the wiring going to the injectors.
Eitherway, IMHO, the place to start is with adding good injector cleaner to your gas tank and see if that helps, oh, BTW, buy like 3 bottles of it, keep the extra in the car and add it 3 tanks of gas in a row. Just one bottle of cleaner could just soften the gunk in the injectors and NOT get it all out, then it will harden again worse after you stop using the injector cleaner.
