Yesterday I changed my gaskets and just my gaskets. Everything ran find, drive around 30 miles with it and let it sit for an hour. No leaks or anything but started it up to a rough idle (500-1200rpm) and screeching noise coming from the engine that complimented it. I assumed it was the PCV that went bad but this morning the noise was gone and the car started and drove fine.

The service light came on during the rough idle. Two codes ran as:

P052B - cold start “A” camshaft position timing over—retarded bank 1
P2096 - post catalyst fuel trim system too lean—bank 1

After doing some research I’m seeing a lot of different things about these codes. Can someone please give their insight on this whole situation?

The noise was identical to this video:

So long story short, can someone tell me more about those codes, and what they think is happening/happen. Thank you
