RPM's reading too high

It doesn't false read. Every modern engine with automatic choke, when started will run on higher RPM for a couple of minutes (or longer depends on the outside temp), until the engine is brought to a working temp. As the engine gradually reaches optimal working temp, the ECU will gradually bring the RPMs down.

the funny thing is even after i turn off my car the needle doesn't return to zero. it sometimes stays at 1000 or 2000. i think you're right though SPEED, it has been 100 degrees almost every day down here.
i thought it might've been reading too high on the tachometer because my dad floored it twice when i was only at 200 miles on the odometer. thanks for the replies

I always wait 'til the RPMs drop to 1000 before I engage any gears or turn on A/C.

that's exactly what happens, sometimes if i accidentally leave the AC on before i shut down the car, it idles high the next time i turn it on. i guess the ecu knows what it's doing...im kinda glad some of you are experiencing this too. sometimes it gets up to 3000 rpm on occasion.
