Hey everyone! I just bought a 2005 RAV4 with 69k miles on it - a rarity in southern california. However, I have since noticed that at times it will idle roughly at random points. Sometimes when I pull up to a traffic light to stop, I will see it go to a rough idle. At times it will stay there, at other times the motor seems to compensate and kick up the RPMs to about 800. Where would you guys start? The motor has been well maintained and is super clean.
