Car decelerates after reaching 60mph. It drives fine until then.

when it’s decelerating, is your foot still on the accelerator pedal?

is/was the check engine light on and/or flashing?

this could actually be engine- or transmission-related at this point

you’ll want somebody to hook up a scanner and at the very least retrieve any engine or transmission fault codes. Autozone might do this for free.

A friend said the “brain” is putting the engine into the “limp” mode. Not sure what to do about that.
