You need to replace the Blower motor resistor, when you turn on your heater or A/C and change the fan speed, when this happens your resistor creates a grond and lets the fan run, so when this blows there is a chance that it will weld itself to a ground and continue the ground circut all on its own even after you turn the vehicle off. You can temp turn this fan off by pulling the Blower motor fan fuse and this will cut the power to the fan completly.
This is a picture of under the pass. side dash...
the arrow is pointing to the resistor, unplug it and remove the 3-4 screws holding it in place. slide it out slide the new one in plug it in and away you go...

These codes let you know the engine is running to lean on gasoline . May be only a plugged fuel filter or weak fuel pump. A vacuum leak can cause this problem . The engine controller may need reprograming with new software. Dirty fuel injectors. Try adding fuel conditioner to the gas tank and changing fuel filter.

The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays.

Check for vacuum leaks, especially the intake gaskets. Does it run rough on a cold start for a few seconds and then smooth out and run fine until the next cold start?
