Is a warm idle of 750rpm bad

The car is fine, never looks to stall. Just read other Rev 3 turbos idle around the 800 900 mark

Is it running well missing or complaining at all.??

I wouldn't worry about it at all as long as the car is running well.

The car is running perfectly as usual had the car 5 years, just read on MR2oc that if it's below 800 a sensor is usually dirt.

Gonna stop being a girl about it and stop worrying :lol:

I thought that 750 rpm is the correct idle speed? I think I've got a Japanese sticker in my engine bay saying it should be 750.

750 rpm

Type of driving..short runs? semi clogged system, air filter ok i'd be thinking throttle position sensor, but first fuel injector cleaner in a tankful of fuel, and check your throttle butterfly is clean/clear as opposed to a ridge build up of dirt impeding the incoming airflow for tick over.

You think 750 is bad, try living with under 500 rpm.

My N/A has a warm idle of around 490-500 rpm.

But it dosn't bother me as it runs spot on and pulls hard through the cogs.

It has cut out on me twice in 1 night when pulling up to a junction. But hasn't done it since i gave it a telling off with my right foot. I think it was maybe telling me it wanted to be spanked lol.

If it's not running bad then I wouldn't worry. Sure a tuner said to me at some point stock figures were plus/minus 50rpm anyway. It's warm at the moment (relatively speaking) so if it feels Ok then I wouldn't worry too much personally.
