1st electric commute in the books and so far I love this car!
Update on the rough idle issue.
After replacing the MAF sensor and upstream O2 sensor it has been running great. No misfires or hiccups, but the CEL came back on. Pulled the code and it's a P0420 which typically indicates a failed cat. While replacing the O2 sensor I did notice that the exhaust manifold (with integrated cat) and hardware looked newer than the rest of the exhaust.
After doing some more digging I have discovered that the exhaust manifold currently installed is most likely for a Cruze and is most likely aftermarket (and thus, garbage). Luckily, it looks as though replacing it will be a fairly straight forward job that I an do in the driveway.
