Ensure your TPS and IAC are set. The below links should
help:

What tach you going by? Stock tachs are junk.....mine reads 300 rpm's to high My car idles at about 800 to 850 in park and in gear even lower 550ish. Definitly do the IAC and TPS, but I think your idling is normal(or my car is messed too)

my car idles at 750-800 rpm
there nothing wrong with it idling low as long as your tps and Iac are set properly

i'd say if the idle isnt jumping all over the place, dont worry about it
