Good afternoon everyone, I hope you are well.



I have a 2004 nissan 350z enthusiast MANUAL, and I have the following problems.

- The car has no power (it costs a lot to raise the RPM), almost impossible to drive.

- Apparently when it is cold it has a good idle / oil pressure, when warm it starts to shake and goes down to 600rpm and turns on the oil pressure light.

- I reset the codes and after a while on they reappear.

p0011 and p0021.



I have tried the following:



- Change all timing chains and their tensioners.

- Change VVTs.

- Change the oil and its filter.

- Change the oil gasket.

- Change the battery.

- Change the injectors.



I'm really asking for your help, I don't know what to do anymore.
