Idle problem

[Picpic]

Hi

I have som idle problems on my Polaris Sportsman 500 EFI 2007.

I start it up (cold) and it idles on correct rpm. Run it for 10 minutes and release the throtle. Engine speed goes down to about 1500 rpm and stays there for about 10-30 sec before it goes down to correct level. Sometimes it wont go down so i turn the key off and restart and then it idles correct. Sometimes when it goes down it idles on too low level so that the engine stops.

I have been running it with a lot of stop and start in cold weahter below freezing point the latest month.

Any ideas?

Maybe a good throttle body cleaning may help or it could also be a tps sensor issue
