Idle Help

I have a 2003 Blazer. Currently it idles at 600rpm. This seems pretty low. Does anyone know what the idle should be and how to adjust it??

Thanks

Actually, if it's an automatic it should idle when warmed up at 650 RPM managed by the computer.....based on crankshaft sensor etc.

When it idles the AC seems to warm up...could this just mean its low on R134 or other problem?

AC Warms up could simply mean low on freon/leak in system.....
