2012 Chevy Equinox. It always starts fine but often stalls soon after. It was getting worse and worse to the point where I'd have to restart it 5 or 6 times. Once it decides it's not going to stall then it is fine until the next time I shut it off.
It was throwing a lot of P0010 and P0011 codes which indicate the variable valve timing camshaft solenoids and are associated with the symptoms I'm having. So I got the ~$100 in parts and replaced them myself. It was a very easy fix, even for a non-DIYer like me (yay, YouTube).
But the problem remains. What else could it be? Maybe a dumb question but I didn't reset the codes--do I need to do that? (Don't have my own OBDII scanner but I could easily get one).

They should clear on their own if the problem is not recurring, but it can take quite a while depending on the code and the amount and type of driving.
But it's faster to clear them and see if they come back.

The OBD codes will only tell you what is ultimately triggering in that chain of events. There may be a sensor or part upstream that is causing that code(s). That's why the home code readers are only so good. you can buy an expensive version, or see if you can get it read by someone with an appropriate reader.
Just a wild thought, but it sounds like an air sensor or similar sensor may be at fault. Again, could be anything upstream of that.

I had some issue that needed fixing, coulda been a check engine light. I was told to put 50 miles on it before getting it smogged, the onboard computer needed to recalibrate itself. My truck had been running normally before and after though.
Hope this is your fix instead of a rerun problem.

Interesting. I was under the impression that a better OBD II scanner would tell you what those codes mean, so you do not have too google it. But I did not know that they can give you additional details. How does that work, are there additional codes that a less expensive reader cannot detect? Some ODB II readers are Bluetooth, and I imagine the iOS/Android software can read most of those codes. I could be wrong though.
The classic example of this is the "bad" O2 sensor, when many (edit: some) times that is only the result of a bad MAF.

Diagnostics with ODBII codes is not always reliable. You may see a symptom that has a totally different root cause. For example.. I saw an "O2 sensor disabled" code. But in reality the catalytic converter was fried. The sensor was fine.

Have you checked the

That would be my first pick as well.
