Whenever the car is idle, it begins to jerk and every now and then it will cut off, but I can immediatlely restart the car. When I am driving (accleraitng) the car runs fine. I took the car to get diagnosed and I was given codes P0171 and P0174. It was explained to me that the computer has recognized a rich or lean condition on one engine bank only and the probable causes are : If bank one and two codes set together then it could be the MAF sensor or fuel pressure, 2, Oxygen sensor defective, 3, Ignition misfire-repair or 4, Fuel injector problem. I read that I may just need to have my MAF sensor cleaned. What do you think it could be?
have the same problem?
