If you want to fix hanging rpms then i suggest you look in the stickies under the how to section and do the IAC gasket mod.

Your engine will idle at around 500rpm. just so you know. Mine jumps around alot after doing the gasket mod. But most of the time is at 500, sometimes dips below 500.

Mine is the same i have 50,000 miles on mine and it acts the same way. and sometimes to save gas when i put in neutral in down hail the RPM stay about 1. so i think its normal and im pretty sure doing that gasket thing well fixes it.
