Default 2007 Poor/Rough Idling Prado 2.7 2TR-FE 4 Cylinders

Hello Guys,

I have a 2007 Prado 2.7 2TR-FE 4 with 79,000 kms

Just recently the engine has develop a Rough Idling where the rpms goes to 500 and you fill the engine shaking. This only happens sometimes, NOT all the time.

The problem is intermittent. I can be driving the car normally, stop at a red light and there is no problem and then I stop at another red light and the rpms goes to 500.

I have check in the engine for vacuum lines and all are OK. I don't have any MIL on the instrument cluster neither any OBD code

I think my IAC (Idle Control Valve) is getting stock or need to be replaced.

Sorry for asking this:
Where is located the IAC valve in my 2TR-FE. I think is attached to the Intake valve.
Do I need to remove the complete Intake valve to have access to the IAC VALVE
Is this is something that I can clean with brake cleaner
Is there any DIY here on in youtube?
Can you point me to a picture of the IAC valve I need for the engine

Thx for your time and help
