If the vehicle is used or driven by different drivers, the vehicle learns and adjusts parameters. This can cause poor acceleration, rough shifting, and more.
When I purchased my use Expedition Platinum, it was doggy, shifted rough, floated like a boat, steering was loose and more. My Son came over and hooked up his tablet and using Forscan, he reset the PCM. The first thing I noticed was the performance, second shifting, steering and suspension. Now the vehicle is using my driving habits instead of the previous driver's.
With that said, if you have access to Forscan, you can reset your PCM. This will wipe out the memory, reset all the parameters of the model you have. I have read that it's a good idea to perform this occasionally. You can also search how to do it manually or I'm sure the dealership will do it for a fee.
