He said car ran well (no codes at all) after the first test drive but he noticed the water pump was leaking pretty bad so I told him to go ahead and replace that while the car was in the shop. After replacing the water pump he test drove again and now the car is throwing a camshaft sensor (P0341) code. He replaced the sensor and the code is still showing up. He has checked the cam timing and both banks are advancing together so doesn’t seem like an actuator issue. Additionally, the car runs well when cold but starts to run poorly and feel sluggish when hot. I don’t think this has anything to do with the water pump install, it just didn’t show up until he got a true test drive with the car all the way warmed up.
He’s keeping the car over the weekend and looking into it more next week, but I’m sort of at a loss for what this could be. I guess this could be an electrical issue with the connection itself causing it to not function properly. Another thought was something is wrong with air/fuel mixture when it gets up to temp (maybe MAF, O2 sensor, injectors...?), but no clue why that would throw a camshaft position sensor code.
Any ideas?
Mechanic is going to keep troubleshooting so will post back if we figure it out.

So in a previous post you stated that the cams on one bank were out of sync. with the other bank by 20 degrees when the actuators were supposed to kick in.
In your newest post you state that your mechanic found no issue with the actuator but the cam timing was off by one tooth.
Did he correct the timing issue????
How did he correct it???
If the cam timing issue was not fully resolved it could be part of the ill running issue when fully warmed up.
Sounds like your P0341 code didn't show until after valve covers were removed and water pump replaced. new sensor didn't fix it.
I would look at the wiring very closely sounds like some wiring got pinched or disturbed in some way.
