Hello benz lovers am new here ,

I have a big problem , after 36 months i was able to start my car but theres some problems now , is hard to turn the engine on and if i press the gas pedal to fast the car will turn off ,i can note that theres a small misfire or jump once i a while .

I pull some codes and the most importants are these :

Socket 8 :voltage suply for LH-SFI control module interrupted

Socket 17 :magnets for crankshaft position sensor not recognized

I have replace: fuel pumps , Maf , wire harness , fuel pressure regulator , spark plugs , caps , rotors ,crankshaft position sensor , all filter and fluids
