I was at a dealership for a vibration issue, we thought it might have been driveline or something (turned out my new Falken Wildpeaks were out of round, all 4). While driving with their drivetrain guy, he said he wanted to get the opinion of the transmission guy - that guy said quite a few people have had issues with stutter and vibration due to an issue with the torque converter. It's most common under load and accelerating, inclines tend to make it worse. He also suggested cleaning the intake sensors, which I did, and it helped the idle greatly.

Same problem on my 2017 Interceptor Utility 3.5 Ecoboost 97k miles replaced plugs and all good. Thanks for the video!!!

Video helped a lot. Thank you for doing the legwork for us.

I have this issue with my ‘13 Flex EB. I had replaced a coil 2 weeks ago and now the issue is back again. The spark plugs didn’t look to bad either but now that you explained it may be time to go as I don’t know how long ago they were swapped out before I bought the suv. Thanks for the post btw

I have an eco boost transit and am having the same problem. I used 93 most the time and am at 92k having mid rpm stutter as well. My first thought (ruling out bad gas) was turbo bad or oil in it but I'm going to try new plugs tomorrow. Van is for sale so if I can solve this prior I can get better price for it thanks for the video

Nice video sir. Happy New Year . And thank I am about to switch out my plug's LOL after 172K. Great little engine. As well as I need to switch out the driver side valve cover. I did have to switch out the alternator do to the valve cover leaking.

I had the same issue you described. Changed the plugs like you suggested and…. Problem solved! Thank you so much for the useful information. BTW, I posted at the Ecoboost group on Facebook and linked your video, just in case anyone else has the same issue.

Sick looking truck bro.

I had a related issue. I changed out my plugs, basically for preventative maintenance and actually CREATED this problem. In fact, the problem was so bad that I actually had enough misfires that a check engine light began flashing and the engine computer shut down cylinders. This resulted in a very rough idle. Once the computer reactivated the cylinders, a smooth idle returned. The symptom didn't appear unless I gave it a decent amount of throttle. I've had the exact same problem occur with my previous vehicle. What you feel can sometimes be described as "spark plug blowout" in boosted engines and the problem becomes noticeable when the engine is under boost. What fixed the problem is actually very simple and I should have caught the issue before I installed the new plugs. The spark plug gap on the new plugs was pretty wide, about 0.040 in or so. My previous car would exhibit the symptom when that gap became greater than about 0.038 or so. The fix was to regap the plugs down to about 0.030 or perhaps a little narrower. It really was that simple. After I regapped the plugs for my F150 down to 0.030, the problem went away. So, when you're putting in new spark plugs, make *sure* they all have the appropriate gap and don't just trust that "the factory" will have preset the gap appropriately.

I have a 2019 Ford Raptor and I've experienced this issue for the past 8- 10k miles. I currently have 56,700 miles on the truck, changed fluids at 51k mile. Initially I thought changing all of the fluids and resetting the computer (disconnecting the battery) would resolve the issue. I accelerate hard from a stop and drive at top speed daily... This first 40k miles I drove 90% highway. Looks like I need to get new plugs!!

I’ve had a few of these eco-boost Ford vehicles and I’ve noticed I have to change the spark plugs between every 30,000 to 40,000 miles or I get that stutter my Ford expedition though I did something different. I change the spark plugs and the coils and it’s going on 122,000 miles now and I haven’t had the stutter again.

Have a 2022 f-50 2.7l with 7000 miles on it and put an oil catch can on it new plugs new throttle body been in dealership twice and same issue. I give it about 3/4 gas around 40mph and up it will shutter and act like a misfire it kind of feels like it’s hitting the rev limiter. The only thing I am starting to think is that by putting 33” tires on it throws everything off or something I don’t know. About to get a lund racing tune so I can just tune and clear codes like my other f-150 that had with the same issue.

Mine started after changing plugs.

I have a 2012 F150 lariat. I have had to change my spark plugs out every 30000 miles. They are supposed to be gapped at .030. Mine when I pulled them out are always .035 or more. I have not tried to regap them I just put new ones in.

My 2011 was at about 106,000 before the original plugs actually got bad enough to throw a misfire in cylinder 3 under heavy throttle, changed them out and put in a set of NGK irridiums and no more check engine light, less than 2,500 miles later and my misfire in cylinder 3 is back, now to change the coils because I know the NGK's aren't bad this soon! 😂 Tho it didn't really have a stutter before the first misfire, but does have that stutter now under medium throttle, all MAP sensors and MAF sensor cleaned, intake valve cleaning done with CRC, so with new coils she should run and drive like a dream 😁

My 2011 did something similar recently, under approximately 3/4 load it kinda felt like a transmission slip. So I got it up on the highway and put the pedal to the floor - that *really* made it angry. I checked the transmission fluid expecting it to be burnt and/or low - it's neither. I wouldn't have thought it could be spark related as the ruck doesn't indicate any misfires. But it's worth a shot since it's about due for a tune up anyway (only has 93K miles on it.)

I also have hesitation if I accelerate beyond 3,ooo rpms. I currently have 78,000 miles on my car and the spark plugs have been changed once already, though I am unsure at what mileage. My plugs already looked fouled and smell like a hint of gasoline, so I know the spark plugs are bad, but the fact that it's primarily hesitating in a specific mph range is alarming to me!

Yes when you tune them it makes your spark plugs last less

Mines been the spark plugs. The 6th cylinder has gone out twice. I rally my truck so they get hot and burn out fast. I recommend every 30-50k replace spark plugs. If you drive like an old man than every 50-60k

I had same problem. Had them replaced, problem went away. But 1 year and 15k miles later, it’s back. Any chance I hit a bad distance plug? Or is it the cables now?

Just found this video and it seems like that’s what my truck might be doing. It started happening whenever my turbo would hit around 15 psi, but it only does it for me when I’m trying to climb hills with or without load. I’ve been forcing a downshift into fifth and a mild speed reduction to get it to stop, but no check engine light has come on. It’s like the engine would cut out with almost a jerking motion. Does it sound similar to yours?

It's that for now and then it will be the coil boots you need to replace them too

I am having a problem with my vehicle now and the transmission fluid was 1 wt low I filled it and it’s shifting better but it’s loss power at acceleration from 0-25ish mph and it’s a 135 k now I bought it at 109k so I’m gonna change the sparkies which I’ve been thinking is the issue

I went with 1 step colder NGK Iridium plugs gapped at .026

i had this problem on my 2015 before but it gave me a misfire code and the tachometer was responsive with the stutter. im having the same exact symptom again now a year later but tachometer is staying perfectly smooth through the stutter and im getting no misfire codes. both o2 sensors are new, so im wondering between plugs and coils, transmission, or perhaps this intercooler weep hole mod ive been reading about. the stutter is as described here, under light acceleration especially on inclines, and feels similar to hitting rumble strips intermittently.

So I have a 2016, 3.5 eco- boost in a Ford Taurus police car. I’m getting that shutter under load also. You can accelerate out of it. Once you get to a certain speed it doesn’t do it anymore. From takeoff speed till about 45 or 50 mph it shutters and the RPMs go up and down 4 to 500 RPMs. This is not flagging an active misfire, but it is giving me a O2 sensor code. So if it’s not firing correctly, more than likely it’s messing with the emissions. It’s only doing it on bank one. P0420. Does this sound about right in everyone’s opinion?
