Possible. If it's stuck open or partially open it won't get up to temp. Watch the temp gauge to see if it gets up to that lovely 200 degree mark and stays there. If it doesn't get that warm, then t-stat is next.

As far as the miss fire, (since the fuel system has been repaired) you could be accumulating some water in the gas tank. Could be coming right out of the pump in this cold weather. You could try to run a tank or 2 of non-ethanol gas (if you can find it). That seems to help mine in this weather when it runs less than perfect.

Keep in mind, the electronics are nice but mechanically these engines are pretty much the same as they were 60 years ago.
