It dies when idleing or somethines while driving. At first it had issues starting had to try key a few times now it starts but dies ive changed fuel filter did an oil change i replaced the camshaft sensor even the o2 sensors i dont know what to do

Oil pressure comes on when vehicle warms up around 30 km driving sometimes throw the engine light on with code P0341. Camchaft sensor problem. Camshaft sensor was changed twice. Cannot figure out what the problem is. It does it when RPM is around 1200. Says engine fault.
