Engine Buck/Misfire at Freeway Speeds on Ford Taurus

The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.

the car will run smoothly then without notice it will chug a few times. This genrally happens at 55 to 70 MPH and when on an incline. It will sometimes happen at lower speeds but doea not seem to do it below 40 MPH.

feels jerky at 40 mph, recently informed the bird chirping noise is the synchronizer making itself known it needs to be replaced,
Engine misfires, bucks and jerks at highway speeds, particularly toward the end of long trips (2- 4 hour trips). Had camshaft replaced and it went away for about 3 months then returned!

Engine misses at freeway speeds. Some relief if car O/D shut off. Replaced all 6 coils, and problem went away for a bit. Started up again after about 300 miles. Most noticable on freeway, and when beginning up hills. If car shifts into lower gear, problem usually goes away.

Feels like my car lurches intermittently while driving. Only notice when driving over 30mph...usually in the 45-55mph range...especially up hill. Feels like when a vehicle is being towed and the slack in the tow rope is jerked. Started happening a few months ago and seems to be getting worse (more often...almost every drive now)...took to Ford today to replace fuel filter but was told it was in fuel tank so not a good option. Have an appt to bring back next week and mechanic take a look at it. Will definitely show them this thread. THANK YOU!!
