    I'm not sure those codes are related to your at speed vibration concerns but maybe they are

    it's most likely a broken IMRC actuator. I just have great luck with timing, first time in 3 years the car has ever felt so smooth and the intake manifold breaks.

    Are you thinking 300 & 308 codes are related to your driveshaft balance?
    Those also do not necessarily point to an intake manifold issue or IMRC issue.
    Hope you get it sorted out

    Let me clarify - those codes are not related. I think the OP knows that and was just saying shit happens.

    Mine does the same thing - Mostly it's related to misfiring on startup, but a new intake to correct it would be OK.

    I'm actually leary of any dealership touching the car to fix anything so, couple those codes with your drivetrain vibration at risk.

    I was reading the thread from the last page backward to see if there are updates.

    I drove 1,690 miles in two days, my GT vibrates bad at 70 and it's crazy annoying, when 70 is the posted speed all over TX. I noticed the vibration when it was new and it will have about 5K when I return next week.

    I have zero faith that Ford can solve the problem so I am reluctant to take it in except to document the problem for a potential buy-back.

    Wow, sorry you have a vibrating 19. My bet is that it's tires. My 19GT is smooth as silk at any speed.

    Just wanted to update, got the car back Monday. Will be driving the car to work for the rest of the week but so far so good. Still missing that vibration that I've felt for the past 16,000 miles.

    So what was the resolution or fix? I mean your post is good that you’re vibe free - but others will benefit from what your Service Center did for the repair. If you can post a copy of your work order that would help others immensely (just exclude the top section with personal info).

    Honestly they just re-balanced the driveshaft that my last dealer put on at like 6000 miles, simple as that.

    So far I've put about 250 miles on the car and its still good.
