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)???? enter image description hereenter image description here

Your mechanic messed something up (or forgot something) as we thought before. It's that shop's responsibility to fix their mistake. Once again, we're talking about a high rpm issue and my first thought is still an oil pressure problem in a variability sensor. (This doesn't mean I'm correct, just my guess). You're going to need to demand that they fix the problem they caused so you don't have to put up with all of this nonsense. And there's the little issue of the fact that it's their job!
