Hello everyone.
Does anyone know the normal idle rpm on a 2003 s-type 3.0 engine? Thanks in advance.

 

I'd guess (!) about 650.

 

Mine idles at ~850.

 

Thank you for your answers. Mine is at about 750 which I think is a little higher then normal.The reason I ask is because I have experienced "the lurch", and have noticed that on lower rpm the smother "the lurch".Is there a way I could lower the rpm myself? Or should I just try a software reflesh? Thank you in advance.
P.S. I remember my 2000 stype was idling at between 600-650.

 

The 3.0 should idle at 700 rpm.

 

Don't reflash, at least not any time soon. Use OBD live data to check LTFTs (see my sig) at idle and at 2500rpm to see if you may have a small air leak, which would raise idle rpm.

 

Thank you for your advice. Will try that when I get home.
