I'd add some Restore to take out any more moisture that is in the tank.

I would say the stock LS1 idles really smooth compared to the earlier GM small blocks---The new firing order really helped in smoothing out the idle--I would think you have another small issue such as an injector going away--or if it is really bad it can be an ignition misfire and could be a bad coil-plug-or wire----

I have a smallish .221 cam @ 114 and it idles smooth at 750 RPM's can't even tell it's in there......

I had my cam sitting our in the cold for the whole winter in Cincinnati. Only snowed and was freezing for about a month, but it sat under a bunch of ice and it is going just fine. Stock they do not really idle too rough. Would look into some of the things suggested already by the guys.
