Default idle speed

what's the standard idle speed on these things. 600 seems a little low but i always thought 900 was a little high. it idles anywhere between 400 and 1700 right now but i'm in the process of fixing and was just wondering where its suppose to be

Is that for all cars, Joel? My emissions sticker says 750 rpms for a 5 speed.

Idon't know. Mine would idle a lot better at a grand...and charge better too. I 'm just stuck on following the manufacturers recommendation of 750. I may bump it up anyway though.
