2005 Honda Civic won't go above 4,000 RPM--CEL throwing P2646 ('A' Rocker Arm Actuator System Performance / Stuck Off Bank 1)
Just got my head gasket replaced, but then CEL came on so I took back to mechanic and he said that he overfilled the oil, so he drained it and said I was good to go. Now it won't go over 4,000 RPM as seen in this video.

Now this happened...
I found this bolt sitting above the thermostat/behind the VTEC solenoid (I think)????
