What is the normal idle at non-sport mode. My car idles between 600 and 700. Is that normal ? Thank you.

RPM on my car is rock steady at 675 rpm in normal mode.

Thanks Frank. Any passenger seat vibration at idle ?

Mine idles at 675 also. There is a very slight vibration; which I would call normal and non concerning.

Slight, in the driver's seat. I have never sat in my pax seat. I have an AWE exhaust which contributes a bit to the vibration.

That's a normal idle. I am not sure what you mean by vibration in passenger. Cars do have a little vibration but not noticeable after driving and warmed up. If you have a rough idle, and considerable vibration bring it in to your service tech and have it checked.

- I've seen mine do that as well especially in cold weather when still not up to temp, the oscillation I mean - slight.... And that has not happened (or at least is less noticeable) since I put in a new battery. I am not claiming it's the reason why, just a comment that it seems to have fixed itself around that time...

- The idle feels rough compared to other modern cars, yeah, and my passenger seat-back definitely vibrates. Car checked out A-OK with low miles and codes pulled: nothing... Putting it in sports mode raises idle to 800rpm and vibrations disappear. I do that when bothered by it.

- It's very likely normal... Don't sweat it unless a light comes on, or if your idle it really unsteady - should not go from 600 to 700 and back to 600 all the time either... If it has a little oscillation when cold, it's probably no big deal. If it still does this with full amplitude when warm, talk to your dealer ;-)

I find it amusing my oldies (carburated of medieval-Fuel-injection) have a rock solid idle but my modern 991 does not ;-)

What miles? Read in various forums that the P engine take some miles before it smooth out, typically after 20k
