2.7L is very choppy from launch

[MJJ]

Curious if any of you are experiencing a choppy launch when you first get moving in your 2.7L. Mine acts like the fuel wants to cut out for a second and then it gets going. It is perfectly fine on the highway. Around town is pretty frustrating. I have 11,000 miles on it so it is likely not the learning of the transmission.

I really didn't want to ask this because I'm sure you know it's a thing but just to be absolutely sure.... it's not the auto start/stop feature right? Because some people don't know about it and that's pretty much how I'd describe it

I've experienced that. A hesitation. Particularly when turning from a stop with a lite decreasing throttle to a heavier throttle. Happens occasionally.

I haven't figured out if it's the vehicle or if it's how I'm feathering it. Turbo lag? Performance tune?

I have this on my new one. The first thought that comes to mind, this vehicle's programming is more interventionist than any other that I've ever had.


It's a bit surprising that 3 years was not enough time for them to work out all the bugs. I tend to view things optimistically. In a room full of crap, I'm looking for the pony. At least I bought prior to deployment of the drunk sensors.

20,000 miles and mine has never been choppy from a launch.

That’s not turbo lag.

It's just the shit 10 spd. Not a learning thing, they're just a really awful transmission.

Quite interesting this popped up, as I was just thinking this earlier. Had mine in Sport mode, drove around town, stopped and grabbed fuel; as I was pulling from the incline stop line and pull into the lane, it felt as if the Bronco had cut out on me or went into Limp Mode. I had to put full throttle onto the skinny pedal in order to dodge a car that was speeding toward me.

Personally, I think it's just the very conservative tuning from the factory, as my 2018 F150 5.0 & 2022 F250 6.7 both felt similar until I dyno tuned it.

Yep, happens with mine. Left turns mostly, oddly.

Thanks for the feedback. My wife has a Wrangler Rubicon with the 3.6. The engine/transmission is buttery smooth around town Compared to the Bronco.

I may try and have it tuned.

Nailed the description of the issue!

I am under the impression of 1) transmission tuning 2) the blend action from port injection (idle) to direct injection (throttle) 3) Sasquatch gearing making 1st gear touchy
Always wondered of the folks that "felt" this way who then went to the FP tune if it smoothed it out.

Agree it's the 10 speed transmission. 10 speeds is a lot and it feels like it is always shifting. "Choppy"- maybe somewhat but definitely not abnormal. I just attribute it to the 10 speed automatic. And it's not "awful" to me. My wife's 2013 Silverado has a 4 speed automatic and it's so smooth in comparison- a lot less gears, longer gears and less shifting.

I would like to take a closer look at your driving performance concerns. Could you please send over a message with your VIN and estimated mileage so I can look into this on my end?

Mines been doing the same thing since day one, very annoying to say the least.
