2010 MKZ factory Idle Speed?

Recommended Posts


I just had my spark plugs changed and my idle feels like its 100 rpm too high, anyone know what the factory specifications are for the idle? I have been through my owners manuals and could not find.


Also can the idle be simply adjusted? Again its feels good but just a hair too high (just questing 150 rpm +/-) on my tach it looks to be around 800 or a hair lower. Car idle's and runs great, its just my personal preference if I could easily drop it a hair if not no big deal..

WRT your question, you're right on the money.  The factory spec is around 725-750 in gear.  You can't adjust it anyway.  The PCM controls that.  If it was too low, you'd get a CEL.  If too high or erratic, that would indicate a problem that needs attention.
