2.4 idling at 1k rpm give me ideas

It's a 2.4 with 66k km. I noticed it's idling at 1k rpm. What could be the cause?

Hi idle at that an more is normal when first started and cold. It will/should drop after a minute or two as its warming up. I don't have first hand experience with that engine.

Details lacking, how long have you had it.
How long has it been doing this.
Location, outside or garage

Less information, less chance of receiving meaningful help.

Cold or hot , or both? - the picture shows its adequately warm to be off the "Cold Start RPM".

Mileage?

When it the problem start, and did it start suddenly?

Did it start after a service?

If the idle is high hot and cold, a typical cause is a vacuum leak in the intake after the throttle body, or if your model uses an IAC/ISC it could be sticking.

Hmm, just looked at the photo, yeah its warmed up and still holding on. Its all computer controlled and only thing might be a wonky O2 sensor.

A code check would be needed at least. But likely need a proper garage to look at the running setting to see if its running rich etc.

But hey, if you can't be bothered, why should I.

To 2.4 owners, is that temp normal for a warmed up 2.4. My V6 after warming locks in at about a notch below 1/2 way on the temp gauge. At the temp reading posted in Tinted's picture (less than 1/4 on the gauge) my car is running 1000 RPM but only stays there momentarily as the gauge keeps rising and the RPM dropping to 6-700 RPM as temp increases.

I find my 2.4 VERY long to heat up...(specially with winter temps we had this year...and compared to wife's Suzuki SX4)...eventually it gets to where it should be ..in as much as I can remember, near half the scale. I.ll pay attention next time .
