i have this same problem on my AE111 levin
everyone says that it is because of a vacuum leak check around your air filter

My starlet had that issue too, however the throttle body had just been cleaned. It turns out one of the paper gaskets had a break in it...

check all vacuum hoses between you air cleaner and your tb. Check throttle position sensor. Remove and clean tb completely, including idle stepper motor.

Have u adjusted the screw that controls the idle thingy?
1200-1500rpm? thats not even that high compared to my car...on cold start mine is like 2100rpm and when warm around 1500

[Red2]

No i havnt really, since i only got the car two days ago and i aint too mechanical minded

Is it even a serious problem having it idle at that rpm?

[Dr-X]

not usually a biggy, not too much of a worry.

If you're quite concerned, take it to a mechanic, it'll be an easy and cheap fix, just go to a good mechanic you trust.
