2005 Ford F-350 Super Duty XL 5.4L Poor Idle Quality, Poor Fuel Economy
Posted to Ford Driveability on 12/16/2008 7 Replies

Help!! Truck came in with mentioned codes. Found at idle both upstream o2's reading 0volts & downstream 1-2 volts. Not swinging at all. The odd behavior is when you accelerate or keep idle above approximately 1200 rpms the O2's will start to fluctuate normally...
