what is the normal idle speed of corolla 2006 model

#1
Hi everyone,

im having problem before with my corolla withe vibration due to low idle speed. It was around 1000 rpm during first start of engine without a/c but upon turning on the a/c vibration will occur and rpm will drop 600. and then as search the internet, I discovered that cleaning throttle body wih throttle body cleaner will help. so did it and the result was Im having 1600 rpm during first engine start and when I turn on A/c it drops the rpm to 1000, the good thing here is the vibration was eliminated.

so i just wanna know if 1600 rpm is normal during first engine start wihout a/c?

hope you can share your knowledge with me.
