I always knew that my air conditioner sapped some power from the Focus while in use. After installing an AEM Wideband and A/F gauge, I noticed that the A/F ratio fluctuates a bit more than usual. Whereas it normally sits at 14.7, it hovers around this point with the A/C on, sometimes dropping as low as 13 for half a second before returning to 14.7. That's drastic, normally it just fluctuates between 14 and 15 with the A/C on though.
Is this normal behavior? I'm not too worried, just curious.
