Apparently Ford thinks they are fixed in the 06 LS.
The valve cover oil leak problem was apparently fixed on the 04 and up models, but not the 03s.
From the R07M07 document
"AFFECTED 2004 AND 2005 MODEL YEAR VEHICLES
Some of the vehicles may experience an engine misfire condition predominantly due to internal
breakdown in the coil and lack of adhesion between the epoxy and the coil housing material.
These issues may cause the coil to operate at an insufficient voltage level, resulting in ignition coil
misfires. Drivability symptoms associated with an ignition coil misfire include rough running
engine, surge or hesitation on acceleration, and/or illumination of the check engine light."
"AFFECTED 2003 MODEL YEAR VEHICLES
Some of the vehicles may experience an engine misfire condition predominantly due to internal
breakdown in the coil and lack of adhesion between the epoxy and the coil housing material.
These issues may cause the coil to operate at an insufficient voltage level, resulting in ignition coil
misfires. In addition, the valve cover gaskets may allow engine oil to enter the spark plug well and
cause degradation of the ignition coil boot, resulting in ignition coil misfire. Drivability symptoms
associated with an ignition coil misfire include rough running engine, surge or hesitation on
acceleration, and/or illumination of the check engine light."
