So I decided to go with checking the fuel injectors, as I had some spare ones from another BMW, the injectors cost are £371 + VAT so a fortune which is why it might be a good idea to make sure its an injector problem. It was in this car so I replace it with the second hand one I had. #bmw #bmwe90 #fuelinjectors #launchx431
