Hi FX45.0,

I'm not a technician, so I don't have access to repair histories or information regarding common issues. I'd recommend making an appointment at a different dealership for a second opinion. If there are circumstances under which you can make the shuddering occur, you may want to bring your tech along for a test drive so you can duplicate it for them. What's the current mileage on your truck?

This is my fear.

I've been around long enough to know that the lugging/jerking issue we feel going up hill under slight acceleration (and I can recreate it in 4th - 6th gear) is *NOT* normal. And this is with nothing in the bed or on the hitch; I would NOT want to tow much at all with this issue.

And while I'm not a vehicle technician, I'm aware enough of troubleshooting procedures (being an IT guy) to know how to eliminate other problems; and it drives me insane when I spend a few weeks nailing down an issue so I can bring it in to the dealership and have it diagnosed and fixed - only to hear "LOL, it's normal."

In any event, I've got an appointment for next Tuesday at 0800. We'll see how it goes.

Has anyone seen this?

I have a 2014 STX w/ the 5.0L and the 3.55 rear end. It has just over 5400 miles on it.

About 600 miles ago I noticed a shuddering when cruising on the highway. Almost like I was going over a lot a small bumps in the road. So I have been watching the pavement very closely to monitor the shudder vs the road surface and it is surely miss-firing. I worked for Brenspeed for 5+ years and know a good amount on both the 5.0L and 4.6L engines and know how to spot a miss.

The truck is tuned and has a Roush intake. I have returned it to stock and have scheduled an appointment for tomorrow. The service tech I talked with said he was aware of the TSB and he said he would take a look tomorrow.

Any of you other members have a tune on your truck and still have the miss-fire when returned to stock. I have yet to drive it with the stock tune.

Thanks

I have the lower shield and 3 trips back to dealer after that. Ford has called me back, once, waiting in another call back due 2 days ago. My advice-- live with it. My mile went to **** ( 12mpg hwy), power went away and shifting is horrible. The have reflashed the truck several times, mileage at about 16 hwy now. I have not towed my camper (10K), afraid to at this point. I bought a Maxtow Eco for the towing capacity and power, they now made it a gas hog no power POS. Might as well lower it and put cheesy *** mufflers on it.

Kung, I know the feeling. Im a electronic/mechanical tech by trade and i know if someone brought there truck or car with a problem i would troubleshoot down to last piece of the puzzle. I know its not normal to feel like your engine is missing in one cylinder or even feels like the tranny is not fully locking up in six gear. Anyways thats why i bought a new truck cause i do not have the time to work on issue like this. The dealer scan tool need to be used but also they should know how to troubleshoot as well! I have own plenty of performance cars and trucks and this issue is by no means normal. its a ticking time bomb!

Agreed 100%. At work, I'm often told that people say about me "If you want work orders done, bring it to someone else, but if you want it FIXED, bring it to Matt." LOL That's because I troubleshoot it until it's FIXED, and if that means months, it means months.

So it drives me insane when nothing's done and it's a 'characteristic.'

Got a call from "Perry," supposedly one of the Ford Regional case managers or what have you. He said about what I expected - keep us in the loop, we'll do whatever we can to assist and make it right, etc. - but getting a call that quickly was nice. Thanks for the help I've already gotten, Crystal - will keep you updated on what happens next Tuesday.

You're welcome, Kung; I'll look forward to seeing your updates.

I have a 2012 Ford F150 EcoBoost and was experiencing the same problems, When I took it to the dealer ( Under warranty ) the first thing they did was install the intercooler shielding thinking it was accumulating moisture, and then reflashed the ECM. Soon as i picked it up I had the same problem. I knew it was a misfire but according to their scanner it wasn't. Only way to have verified the problem was for the check engine light to be on when I brought it in. So I ran the crap out of it while it was misfiring and that sparked the Check Engine light to come on, I took it immediately back to the dealer and without shutting the truck off ( Which will reset the Check engine light) I had them scan it... Sure enough It was a misfire on #6 Cylinder and as a result we changed the Coil Pack and Spark plug and this fixed the problem, haven't had another issue with it since (8 months ago).
