1998 Mercury mystique 2.0, I have replaced wiring harness, pcm, thermostat, temp gauge sensor, fan sensor and here is the problem. The check engine light is on showing bank one lean. Now here is another problem when you hook up the wire to the fan sensor the air conditioner stops working and the fan runs at the high speed. Unplug the wire and air conditioner works. I have tried everthing I know to fix but no luck HELP
