Drivability has improved.
It helps to let it warm up a few minutes, starting and taking off is a habit I need to change. The lean shutter is almost undetectable and I'm about convinced, after reading here and talking with performance shops that a tune would solve this completely and probably improve fuel milage.

I'm not interested in drag times, just smooth efficient operation.

Probably not a good choice in replacement vehicle.....FIAT is ruining Jeep.

Mine was a POS that i bought new and owned for less than a year. Was in the shop more than i had it.

Should have lemon lawed that months ago.
FIAT = Fix It Again Tony!

Best,

I agree that Modern engines and oil are an engineering masterpiece . .. then I see post about adding oil cans I begin to wonder. I am sure that the engineers added a fudge factor and I know that the Europeans think Americans are nuts to change the oil every 7K miles. . . But I would rather be early than late. :) this is the last truck I plan on buying, so I will do maintenance a little early :) Maybe P. A. Schilke will comment on this :)
Hi Mark,

Sorry, was on the road in my RV and must have missed this post. The engine engineers and the program agree on an oil change interval, and the program pushes 10K mile interval...Engine Engineering then counters with what it takes to ensure robustness for 10k...Then the program folks will usually say this is not affordable and will accept lower mileage. With today's PCM, there is an algorithm for dinging the owner with a Change Engine Oil Soon based on how the vehicle is used...I recommend waiting for a Change Engine Oil Soon warning...You have about 1000 more miles before the warning changes to Change Engine Oil Now! Durability testing is done on the agreed interval with the caveat to change oil more frequently for severe duty environment. It sure does not hurt to change oil early, but waiting for the warning is probably best usage of oil life.

Used to be an opacity sensor in the oil pan, but no more...

As for adding an oil catch can, I would not waste my money on this as the engine is tested without one to the tune of 150,000 miles of usage for a 90 percentile customer...that customer is like UPS, Purolator Currier etc delivering in LA city traffic for example. The PVC system is revised for Direct Injection as a result and should handle the lack of fuel passing through the intake valves.

Hope this helps

Sitting in the dealers lounge and the service advisor tells me that this engine has a known characteristic that around 1500-2000 rpm that due to EPA/emissions regulations there is lean spot that is causing this miss.

There going to plug it in anyway and see if anything shows up.
Offered to let me drive another Ranger to see it has the same miss.

:(

Wait and see, they’re working on it.
I have had my Ranger in the shop numerous times for this shutter. On Tuesday a Ford factory engineer test drove my Ranger an said it drives normally like this. WOW! if that is their answer they must be numb. I have resentlly driven nearly all of their other vehicles available and none of them studder, chatter, stumble. FORD says this is normal??? Not sure what is my next step .......just very frusterated with FORD a company i have been loyal to for 50+ years.

As mentioned above, that TSB helped and a tuner may fix the problem all together.
Other options that I’ve read on here is hotter coil packs from Acel and having a look at your fuel injectors.

Honestly I think fuel mapping using a tuner will clean up all the factory EPA restrictions which is most likely causing this stumbling.

I left my truck overnight at the dealership, so that they could replicated the situation. One week after they told me just drive it and that there where no TSB's on my truck; all of a sudden there WAS a TSB. Even though I never had a CEL, it did have stored codes this time. What I think the problem is, is an out of spec injector, I think the TSB adjust the pulse width on the bad injector when it's cold to put an electronic band aid on a mechanical issue. My truck is now better, but not fixed. Now it only has a dead miss for the first 1000 feet in the morning instead of the first 2 miles.I will have to take it in once or twice or three times again until they decide to actually replace the bad injector.
Any positive update?

Nope, The mechanic who they give it to has no fu#ks to give about it and the service manager practices no oversight. I have one more
free oil change and the truck will be going elsewhere for service and repairs that I don't do myself.

Mark is the shutter/ stutter you're experiencing a feeling like the truck does lurches while accelerating right after turning it on? Mild or heavy acceleration? I get this weird total drop in power as I was driving a manual and taking a big delay to reengage the clutch after changing gears. It's totally smooth, no clunk, no vibration, just what feels like a loss of power momentarily.

I can only get this to happen when I leave work, either end of day or middle of day for lunch. It's the craziest thing. Doesn't happen first thing in the morning from my house, or on weekend. Which might be attributed to I live on a residential street with a stop sign 40 feet from where I park, so i can't accelerate much. But at the office I have to accelerate into traffic from street parking.

One think I may have noticed is when this lurch happens, the big fan noise isn't present. Probably a total red herring, but it's all I've got to go on right now.

No, my shutter only occurs from a cold start when the ambient temperature is about 60-70 degrees and under light throttle; it is a dead engine miss on one cylinder. if the engine is warm or the ambient temp is out of that range, the problem does not occur.
The problem you are describing I have also at times, but is unrelated to the engine miss. I think I have narrowed it down to a 2nd to 4th gear shift under light throttle. it's as if you have let completely off the gas and then dumped the clutch into 4th (like you described); sometimes its a smooth shift though, but sometimes it slams hard into 4th.
I got my last free oil change last week from my dealership and I will no longer be taking my truck there for anything other than recalls. Like I said before, the mechanic they give my truck to for drive-ability issues has no F%$ks to give about warranty issues. I do have a very competent Ford mechanic at his private shop that I will have look at it as soon as it turns warm again.

I'm thinking I have a bad injector. When I first picked this truck up from the dealer this Tuesday I notices a pronounced engine shutter when accelerating lightly and while coasting back down. I immediately mentioned it to my salesman who had followed me home in my car to drop the truck off at my house.
After getting back home I drove the truck again, it was physically making me ill from the shuttering. I took the truck back to the dealer the next day and talked to the sales manager (my sales guy was not in that day), I told the manager about the shutter and he asked me if I wanted to drive another ranger with a similar set up 2WD, XLT; I knew just as soon as I hit the gas on this other Ranger that this other truck was smooth and had no shutter like my truck. I had the manager drive mine at the same time, he confirmed he felt the shutter and set up for a mechanic to look at it the same day.
I pick the truck up later in the day and I was very disappointed to find that the mechanic had done nothing and I was told that the truck needed to be driven 500 to a 1000 miles for the transmission to adapt. While I agree that the transmission was shifting weird also, I knew that was not the only problem, I asked the service manager to explain the shutter, and to why the other ranger I drove did not do it. He said this is what Ford said I should do.
I should also mention that I am a serious gear head and an ex Ford mechanic (drivability specialist), so I do recognize a problem when I see one.
From most of what I have read on this forum, most speak about how smooth this drive-train is. The transmission shifts have for the most part sorted themselves out, but the shutter remains, even more so when the engine is cold.
I know there is a TSB or two concerning this problem on earlier build dates, my fear is this same mechanic will say they do not apply to my build date an yet do absolutely nothing again. I had problems with this same mechanic at a different dealership about 18 years ago concerning my Snap-On Box truck (he caused the truck to be down a week longer than it should have).
My question to the group is, does anyone have any advice as how to get this problem fixed ASAP without causing much drama at the dealership? I sooo miss my 2011 ranger I sold a day earlier.
I just got the truck back from the dealer, I had shuttering on a cold start only. Ended up being a bad plug causing misfires. They replaced all the plugs and I haven’t had an issue yet.

It's nice that you have a dealership service department that gives a damn, you're a lucky guy.

2019 ford ranger fx4
well, i now have 10,000 miles on my fx4 ranger xlt. 4x4. as much as i like the truck, i also dislike it. here is why, it never feels settled in as you drive it, it shutters all the time going down the road. i have made numerous calls to ford about this issue, and all they do is document what i state. they need to be up front and fix this issue, with all these 4x4 rangers. i have taken it to the dealership 2 times on this issue, end result is this is how they drive. i know its not the dealers fault, thats what they are being told by ford. ITS BS. for the hard earned money that i paid for this truck it should run and drive smooth, but it don't. i invite all ford engineers to call me 419-307-8713 and tell me that ford is going to fix it.

Call customer service.
Mine had a stumble when new but now it has gone away, 13k miles. Can’t explain why but its smoothed out. Surely it didn’t take this long for the transmission to learn my driving habits.

i'm curious where the misinformation about the transmission learning specific driver habits comes from.
its still runs rampant in the forum.
did the sales people get mislead during the pep rally at the sales conferences when the Ranger was making its way into the market? passing on this bogus miracle transmission brain to the new owners?
was there a misprint somewhere in the documentation?

either way, it adjusts itself for manufacturing tolerances and probably for wear over time...nothing more, nothing less. it does not distinguish if your male, female, old or young, baby the throttle or mash the shit out of it.

Automatic Transmission Adaptive
Learning
This feature may increase durability and
provide consistent shift feel over the life
of your vehicle. A new vehicle or
transmission may have firm shifts, soft
shifts or both. This operation is considered
normal and does not affect function or
durability of the transmission. Over time,
the adaptive learning process fully updates
transmission operation.
Two Service reps from two different dealerships told me that when I complained about my stumble. Both times they preformed the TBS on the tranny. Cleared up for a while then came back, both times were under 8k miles.
All seems well now since Im past 11k miles.
