What do you to clear dash code 52 on a 2013 Chevrolet sonic ls sedan with 1.8 liter ecotech motor
What led you to change the ignition coil and plugs? Were they confirmed faulty?
Code 52 means your timing belt needs to be replaced. A worn timing belt can and will cause a misfire and other problems. At what mileage is your Sonic now and at what mileage was the timing belt last changed?
P2076 is related to the intake manifold tuning (tuner, or switch, or runner control or valve). The tuning valve is a motorized actuator attached to the intake manifold. An issue with it can cause misfires and other issues. It'll need to be tested for a problem with the actuator itself, or a problem in the actuator's circuit (i.e. wiring).
I recommend having the timing checked and the belt changed as needed, and tackling the P2076 afterward, if it hasn't resolved itself.
2015 Chevy Impala 3.6 l upstream o2 sensor
You have 2 of those and also 2 downstream. You have two banks of cylinders and each one has an upstream o2 sensor and it is located in the exhaust manifold for each bank. Your scan tool should say Bank 1 or Bank 2.
The downstream sensors are after the catalytic converter.
What are the symptoms of a bad upstream O2 sensor?
Sensor 1
Sensor 1 is the upstream oxygen sensor. It is the sensor that measures the oxygen content in the exhaust, providing an input to the computer, which determines how to adjust the air/fuel ratio. Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor.

2004 Chevy Trailblazer 4.2. How do I get moisture out of my breather box
That could mean your PCV valve/system has a problem and isn't removing excess pressure from your crankcase.
During the power stroke of the engine, the gasses from the crankcase are forced upward, and if the PCV isn't functioning properly to route the gasses to the intake to be burned, the pressure will push oil upward past the piston rings and into the intake.
I'd start by checking/testing the PCV to make sure it's functioning properly. If you have a PCV valve, it may need to be replaced.
