Idle speed for 1995 3.1L Lumina

Hello,

Just purchased a 1995 3.1L Lumina and don't know much about these cars.

What is the proper idle speed at cold start and warm idle?

Right now the car idles on cold start around 1100rpm and warm idles around 900rpm.

Seems like the warm idle should be slower.

Thanks.

Nop, we have to Luminas 98 3.8L one ist when its warm on 1000 RPM and the other on 900 RPM.
