pls help , my Yaris has problem !

[IllusionX]

Have you done any maintenance to the car lately?


The Yaris does rev up to 2000rpm idle when it's cold outside, and will drop to about 600rpm once fully warmed up.

Are you saying you have a check engine light? Might want to have I checked if you do.
