Acceleration problems
Hello i have a 2014 is 350 rwd that sometimes does not accelerate as fast as possible at full throttle. i have cleaned the throttle body, maf and air filter
I have discounted the battery to calibrate the throttle body but nothing the throttle body opens around 64 ° but when I have the problem there will only be 30º

How are you determining the throttle body opening percentage/degree/angle?
Any warning lights on the dash while the condition occurs? Possibly flashing.

Hi
It determines it through my scanner but not a warning light or check engine. I press the accelerator fully the throttle body opens half but when I fully release the pedal and press it again the car pushes as it should

Do the RPM still rise even when the car isn't pushing like it should? Does the speed increase when the problem happens?
How long have you had the car?
Throttle angle will never reach 100% when fully open...I think it will show somewhere around 70-75% when it's actually fully physically open. Don't ask me why they measure it like that.
Any chance you have a video of this happening?
Honestly I'm still trying to understand the perceived problem.

Hello, it happens to me to drive by repeatedly pressing the accelerator fully as the speed increases, but as a 300 hp car should do, I have had the car for about 2 years with the proper care.
