Help Diagnosing Slew of CEL Codes

He put the car back together and it runs MUCH better now and I was able to drive for an hour yesterday with no codes.

Unfortunately, eventually a CEL code came back for bank 1 timing adjustment. I think the actuator may have been damaged due to lack of oil or is working intermittently. Going to drive it for the weekend if the code keeps coming back we will put a new actuator in and hopefully have this issue put to bed.

Sounds like your making some progress as things are beginning to improve.

It’s running way better, but still randomly sluggish off the line which I think is due to actuator just not responding correctly 100% of the time. I had a blast last night cruising through the mountains though, so definitely making progress .
