I need to get some additional information from you. First, the codes indicate a misfire on every cylinder, so that can certainly cause low power. The two other codes are also if interest. The first one deals with a heated oxygen sensor. The other one, P0340, deals with the camshaft position sensor "incorrect allocation."
Anytime I have seen that code, it has been due to a timing belt being off by one tooth. That will certainly cause a power issue as well. Has anyone done anything to the timing belt? This could also cause the misfire codes.
I attached two pics below showing timing mark alignment marks. I need you to check this and let me know if they are correct.
Let me know
