2016 Buick Encore rough idle, stalling and check engine light.

This 2016 Buick Encore came into the shop idling very rough and surging. Check engine light on and intermittently stalling. Diagnostic codes included P0131 which always would be the first code to populate after clearing and then restarting. The code is O2 sensor 1 low voltage. If your vehicle is exhibiting these symptoms check the disc on top of the valve cover first for a vacuum leak as shown in the video. If it is leaking the valve cover will need to be replaced. This disc is the vent valve for the crankcase and is a mandatory function for the engine to operate properly. This particular vehicle had 80K on the odometer. The engine is a 1.4L turbo.
