Given this information is it possible the variocam actuator and solenoid I was sold was a dud and its sticking when activated which explains the car idling great sometimes but like trash other times, and I assume the following missfire codes are the car adjusting fueling to compensate for the bad timing leading to a missfire. What i do know is when I hit the gas the car revs smooth and goes like a boxster should. I know in the future i was planning on replacing my 116,000 mile old ims bearing and also replacing the trans fluid in the tiptronic so maybe I should just drop this engine for an overhaul? I dont know what to do at this point ive alredy taken off the passenger camshaft cover off 4 times becuase the first time I used too much sealant and the plugs popped out, the 2nd time a bolt broke and i had to take everything apart to extract it, and now I am guessing the worst that my "new" camshaft actuator/solenoid are garbadge and I have to redo the whole project.

Odd situation.
Have you replaced the Cam position sensor on bank 1 yet?
When you replaced the Cam actuator/solenoid did you check to see if there were the proper number of chain links between timing marks on the Cams?
