When the engine is cold it starts and runs perfectly fine, but after twenty or thirty miles it seems power loss and eventuly end stopping and automaticaly turning off the engine. I have changed the cam sensor and the crank sensor, after changing them two it worked three thousand miles on and off, but now its happening again. I am getting the error code P0171. Have no idea what to do just hoping that you expert might help me in the right direction. Have also changed cat. Thank you for your help, looking forward to hear from you in the near future.
