Stuttery/hiccupy acceleration after cold start

[CajunMick]

I like my little turbo and yes I will change out the two inch long turbo oil filters that Ford does not mention. I’ll do that at 50,000 miles. Cost is about $300 @ Ford.

I cannot imagine ever owning a 4 banger without a turbo now that I’ve got this one.

V-8 power out of a 2.0 Ltr 4
OUTSTANDING I say !

That’s great. Turbo puts small engines on steroids.

In the past, had couple 4 cyl vehicles. Never complained of their performance.

My neb has a late model GMC SUV. Had to replace the turbo. $6,000!! I told him prob can replace engine with long block. I had a van, Pontiac, had a broken cam, one of those cheap hollow one with press on cam lobes. Had a shop put in remanufacture long block for $4K. These engines have history of cam failure. GM/Pontiac offered zitch assistance.

Modern Direct-Injection Cars: Italian tune ups are mostly ineffective for cleaning the intake valves on modern direct-injection gasoline engines. Those valves do not get hot enough under regular high-RPM driving to burn off heavy carbon deposits.

2. The Redesigned 2.0L EcoBoost (2025+)

Ford updated the 2.0L EcoBoost architecture for the 2025 model year to incorporate their Dual-Injection (PFDI) system—adding the port injectors upstream to eliminate that legacy carbon issue once and for all.

Don't you be trying to take away his fun-factor excuse!!!

Mario is behind his left shoulder while he drives whispering "harder on the throttle".

I will never own a GM product again.
They often farm out warranty work.
Up here it’s 100 miles away. Adding two days to any repair,
And it’s done at a off the wall shop called a warranty center, not even a GM dealer
Screw em’

All I know is my seat of the pants Dyno tells me after every Italian tune up my Ecoboost is more responsive and smoother.
At 4,300 miles it’s starting to break in really well.
I’ll only do it once every thousand miles now.
Could be the computer readjusting to my off the wall throttle presses.
IDK

Oh good, I’m glad it’s normal then so I can stop worrying about it, lol. Thank you.

Exactly what I Thought !

I've had this exact issue as well. Changing my RDU fluid took care of 95% of the problem. The initial acceleration is still a little "weird" but it's significantly better compared to before changing the fluid. Shifting through the first few gears overall is noticeably smoother now.

The fluid was properly filled from the factory, had lots of debris in it and I changed it at 33,000 miles.

My 24 does the same stutter/jerk, I just let it warm up longer on cold days and dont notice it.

I think it is just a odd model specific quirk.
