i30 high idle issue

[Locry]

Hi,
Total noob here. I have an i30 with a 2L V6 engine. Lately it has developed this intermittent high idle... 2000-2500.
Restarting the engine will normalize the ilel for a while, but then it'll climb back up again. But there are times when the idle is completely normal.
I really have no experience with computer controlled engines... I used to have carbed small block chevys and a few mercedes diesels.
I don't have access to a scanner and can't commit to bringing it in to a shop at the moment. If there's anything I can do or clean up at the moment i'd like to try.
Thanks...

Keywords: INTERMITTENT... restarting causes the idle to normalize for a while

Further reading point to the IAC for some cases...
IF it's the IAC... does restarting the car allow the idle to normalize?
Anyway... anybody have any tips on how to actually get to and clean the IAC?
Thanks again

You can start by cleaning the Idle Air Control Valve
Don't use carb cleaner use electronic cleaner
I know on the 95 maxima you can unscrew a housing which covers the valve
The time i did it corrected the problem as there was excess carbon
I don't think Nissan provides detail to do this -this was what NICO people figured out

Go to the FSM website to find the valve

Thanks!!! It's on the throttle body correct? I don't want to mess anything up and render the car unusable... is cleaning pretty straightforward? No little things to break?

BTW, it's an A33... do I have to remove the throttle body? or can I just remove the IAC in situ?
