JimD Posted September 23, 2007 Report Share Posted September 23, 2007 I would advise you clear the codes, take a short test drive, and read the codes again. If the P0171 and P0174 return, you have an intake leak that is allowing unmetered air to be pulled into all the cylinders; both codes indicate a lean condition. Jim Drive your car.
