unless the car is at operating temperature , the engine rpms on start is hiogher the at run as the ECM has a higer setting for idle ( like having a choke out a bit ) until the engine checks are done and then it settles back
best run the fault codes to check for faulty sensors

Cars are design to run at a higher idle at start up to warm them up quick. There is a sensor that reads water temperature and tells your car's computer how fast to idle. Your RPMs seem slightly high but not out of the norm. Does idle ever drop to around 600/800 after about a minute? If not, your engine temperature sensor maybe defective.

It can be issue with IAC( idle air control valve) causing the problem.

There are many other possibilities causing these idle issues. Engine idles rough.

There are few help links with solutions to troubleshoot such idle issues.

I suggest you refer the link below and follow its troubleshooting details:------

These details will help.

Thanks.

Your idle should pretty much be set by the computer and shouldn't change to much unless some repairs have been or you have another problem. In any case below are the instructions on seting the idle. Also below I marked which fuse you will need to pull out for about 10 seconds in order to reset the computer. Make sure that if your radio has a security code that you have it before you pull this fuse as you will have to reset it. Hope this helps.

try replacing your idle control censer it is normal for a car to idle high for a short period when it is cold but only for about 60 seconds

sounds like the trnsmission filter may be plugged or the ports in the tranny may have clutch debris in them, either way it doesn't sound good..

Its could be a few things. Most likely cause is you IAC (Idle air control valve) If this valve gets clogged up with carbon it will cause a idle surge on cold starts like you are describing.

Next your FITV (fast idle thermal valve). When the hot wax inside of this valve starts to wear it will cause a idle surge on cold starts.

I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck

sound like catalytic converter when it is night time and you have just arrived somewhere quick get out raise hood and look to see red glowing coming from the exhaust manifold.
