Low RPM when Idle

[esse10]

Mine is also about 600 at Idle and too low in my opinion. Most manual tranny cars should have an idle of 800-900 rpm. Does anybody know of how to increase the idle rpm without having to visit the dealer and their expensive fancy Computers.. ???

that is total bs. I know you are long gone, but for anyone still reading, many cars idles are very much mechanical, not computer controlled. Not sure if the stock Yaris is mechanical or not. I'd love to know though.

If it is mechanical you could set it higher. If not you cannot. The Yaris comes from the factory to save as much gas as possible. An extremely low idle helps.
