2008 sebring 2.4l idle speed
 

Had the plugs changed and the air filter changed at the dealer. (27,000 miles)
Idle is at 800 rpm with the a/c on (max recurlation setting)
Is this a noraml idle with this car ?
On the old plugs, used to be at about 700 to 750 rpm with the ac on.
This increase cause of the new plugs and air filter ?
Same plugs were put back in the car ngk's.
Idles nice and runs great.
Thanks in advance.

spark plugs dont change the idle speed of a car

Idle speed is controlled by the engine computer. It takes into consideration several factors including A/C load, power steering load, engine temperature and air temperature. As Tech says, plugs don't change it.

Went back to the dealer today and under warrenty one of the coils was replaced and the iac was changed due to sticking.
All under warrenty.
