2004 Ford F-150 Lariat 5.4L Poor Idle Quality, MIL Lamp on
This F-150 has Lean DTC's and A/F and O2 Stuck lean DTC's for both banks. Has a rough idle, occasionally stalls. Restarts no problem and seems to drive fine off idle. Short term fuel trims are maxed out at 45% and still no voltage output from the Oxygen sensor...
