I bought a Panamera 4s 2010 that had a front collision. I have a reduced engine power light that goes on.
I have replaced the world and still can’t find why it has a rough idle and after a bit kicks it in reduced engine power. I have replaced the high-pressure fuel pump and the low pressure fuel pump, the Fuel filter, and a fuel rail sensor, and The water pump and the thermostat and the timing chain and guides and pulled the top head and replaced new value guides and gasket kit. And New Radiator and condenser.

Any ideas!! Thanks in advance!

I did hook to carly computer reader and codes were
P0135
P1023
P2243
P2a00
P2298

We did replace the high-pressure and the low pressure fuel pumps, the fuel filter and fuel sensor. The o2 sensor error is new.
