Random diagnostic codes

My '16 has been throwing various codes which continues to get worse. Initially, it started with the crankshaft position sensor "A". I replaced the sensor and then received the same sensor code plus:
multiple cylinder misfire
cylinder 2 misfire
cylinder 4 misfire

Today I changed the sparkplugs which were due to be changed and now getting:
Intake Air Temperature Circuit High input
Mass or Volume Airflow Circuit Low Input
Ex Cam Angle Sensor Signal High
Camshaft Position sensor "B" circuit High Input (Bank 2)
Crankshaft position sensor "A" Circuit high input
Random/Multiple Cylinder Misfire Detected
Cylinder 2 misfire
Cylinder 4 misfire

I'm wondering if this could be the coils as I did not change them yet. Or is it time to just have the dealership have a look?

 

Sorry to hear about your issues. Sounds like it might be more electrical related vs hardware related? ECU or wiring damage? I've got almost 300k on my stock coils.

 

Yeah, you're probably right. It definitely seems electrical related. Which makes it a pain to troubleshoot.
