any harm in setting idle at 900rpm?

 

Nope, I found it kind of annoying to have it that high though. It was a little the noise but a lot the way it'd pull setting at traffic lights. I upped mine a little because it was running not very smooth with the A/C on in drive. I ended up lowering it back down close to where it started at but now it only goes below 725 (supposed to be 750-800) if the A/C is on max while in drive.

 

just got done turning mine up to 1000 rpm ac on and in park. now she lights up with just a touch of the starter,and settles down to @800rpm in drive

 

Got mine at 750 with AC on

and already warmed up.. in gear....
