Just got my exhaust sealed up finally. Minus the catalytic converter... Sometimes I hardly have any power at take off...I'm getting codes, P0300 P0030, P0340,P0302, P0301, P0135,P0304, P0303, Now, how can I get these codes to stop so my car will run better and stop acting like it's going to shut off? I've changed plugs, changed oil, replaced a ton of vacuum lines.. i know it's long I'm sorry but I really appreciate you guys helping me. Thank you ahead of time...

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
