my 5.4l gas motor does not start the odd time.you have to spin it over 2 or 3 times then it fires up and runs fine.this only happens 1 or 2 times a week.its a 06 model with 40k on it .thanks

Welcome to FTF.

I don't know much about these motors, but a few more details about what it does when it doesn't start might help the more knowledgeable members here help you. Does it turn over at normal speed and just not start? Or not turn over? Any check engine lights or other strange symptoms?

FORD: 2006 F-150
LINCOLN: 2006 Mark LT


This article supersedes TSB 06-10-8 to update the Action required.

ISSUE:
Some 2006 F-150 and Mark LT vehicles equipped with a 4.6L or 5.4L engine may illuminate the malfunction indicator lamp (MIL) with a diagnostic trouble code (DTC) of P0606. Some vehicles equipped with 4.6L and 5.4L engine may exhibit a high idle or fast idle conditions and the 5.4L engine may exhibit an intermittent hard start.

ACTION:
If a vehicle exhibits DTC P0606 with no other DTC or driveability concerns, clear the DTC, restart the vehicle and run KOER. If the P0606 returns after the retest, perform normal Powertrain Control/Emissions Diagnosis (PC/ED) diagnostics for P0606. If the DTC clears, or the vehicle exhibits the high idle, fast idle, or hard start concern reprogram the powertrain control module (PCM) to the latest calibration using IDS release B44.12 or higher. This new calibration is not included in the VCM 2006.7 DVD. Calibration files may also be obtained at www.motorcraft.com

NOTE: THE CALIBRATION ISSUED IN THIS TSB IS THE SAME VERSION USED IN TSB 06-19-3. ONLY ONE OF THE TSB'S MAY BE CLAIMED PER VEHICLE.
