why too low, burning less gas than a higher idle

but isnt normal idle at 700

if the engine isnt stalling theres no big deal, is your AC on, usually higher when you have it on. Theres no such thing as a normal idle, if you can get it lower than everyone else more power to you, burning less gas at the traffic light

i dont think the timing is right. car feels slower than usual

bagwell

I can't even tell mine is running at idle.....smooth as glass....I have to check the tach just to be sure its on!

Idle is controlled by the ECU. If you believe the idle speed is where it shouldn't be, have a mechanic check it out. As noted above, many things can affect idle speed. 500 RPM's is perfectly fine.

I think someone is new to how well Toyota/Lexus engines are at idle.

mine idles at 650 with ac off.

My 350 sometimes idls at 500 when sitting at a light for extended periods of time. No big deal. Seen this in many cars.
