I have a BMW 528I 2000 with loss of power and shuts off, At first it had 12 codes and I changed the ignition coils and spark plugs and now I'm down to 1 last code P0340(Camshaft Position Sensor A Circuit Bank 1 or Single Sensor, I have changed the sensor with a non oem FCP euro intake and it shut off right away. I ordered a oem part from BMW and installed it and the car doesn't shut off but makes no power at all to move. Does anyone know the fix for this? Thanks
