I am sorry for the long wait
how does it run at idle and when driving down the road ?
at idle is there any noise at all from the timing chain front cover ?
with all new sensors and it still setting these code and the oil is full very common the issue is too much play in the timing chain or the chain has jumped just 1 tooth which would set the codes and also cause the lower power issue
with everything you have done the only thing left is to have the timing cover removed and more than likely the timing chain replaced on this engine
such an issue they sell timing chain kits for these engines
it is best to fix now as very soon the chain will jump more or break and can damage the engines valves if the cam to piston timing get more off than it already is
how are you making out ?
