Bucking while driving.

[silverflash]

Have noticed a sort of bucking while driving. Doesn't matter in sport mode or drive. But if my foots on the gas it seems to do it. I tried driving it with sport mode and shifting gears and zero issues. Only seems to do it when it shifts on its own. Seems like it's either shifting then bucking in-between or just having a misfire. No lights. 2500 miles. 21 fx4.

Lots of posts about this lately. Is it humid where you are? Wonder if it’s the condensation in the intercooler that affects ecoboost motors.

As an experiment I laid into herin sport mode from a stop and got to 60 pretty quick and every shift was smooth and perfect. Perhaps these just don't like easy driving? And it is humid here but not crazy. And not too hot- mid 70s. Mountains.

This is beginning to feel like some kind of coup by the “Fuel in oil” people since that topic has kind of fizzled out.

Yep-cuz we needed a transmission that does that.

I have a 2020 ford ranger lariat has about 67xxx miles now but at around 50k I had the serpentine belt pulley break off the timing belt cover for unknown reasons,they couldn't figure out what caused it so they replace the broken part along with new belts and pulleys now I'm at 67xxx and the truck started bogging down specially in the morning I let it warm up for around 10 mins or so and I start driving it but once I come to a stop light and I give it some gas it'll start moving then bogs down for a milli second and jumps back to speed and it'll be fine after about 30 mins of driving without zero issues,I recently had gotten it back from the dealership and they couldn't figure out the cause they did a pcm and transmission update and didn't solve anything then they replace the tps sensor and battery and they said it was good to go and now that I'm driving it the problem is still there!!now I don't know if I should take it back or do the lemon law anyone else having that bogging issue? its also has the extended warranty.
