your check engine light will be on untill you get it fixed with a HP tuners program... some people never had the problem but some did.. its your second 02 sensor you need to get disabled or it will stay on.. and some times blink at you..
your idle hunting is either like RFOGALX said a Vac leak or your IAC is pooched.. in which case its a simple $6 (i believe) fix and the vac leak could be as cheap as tighted the bolts that hold it to the head...

check to make sure its not space between the tb and the actual supercharger that made my do the same thing one of the botlts wasnt tight enough and it casued a serious leak. also like said above check vac lines.
