Typical CAS symptoms?

[Zufelt]

Hey guys, for quiet some time my car has always had a "studder" before it starts as Shown in the video (listen closely). But recently when it starts up it feels like its running on two cylinders, and after a couple seconds of being on the gas a tad (in nuetral) it will rev up and idle as normal. There has been one time I wasn't able to make it idle right after doing this an it threw a code for the CAS, does this seem like it would be a normal CAS problem? Also, the time I wast able to make it idle normal it died and took forever to crank, which I've read would be the CAS but that was that one time and idiot believe is related.. Also, at times I will slightly rev the engine 3500-4500 rpms, let off the gas and it will come close to dying, if not die. I'm just trying to find a place to start, BLT was done and checks out.
