Hi There, Depending on what specific vehicle you have, this may be caused by a number of things that may have caused the vehicle to go into a fail safe mode or "limp mode." This can happen when the vehicle’s computer detects a problem with an engine or transmission malfunction. Typically, when this happens this will also cause a check engine light to be illuminated in the dash and may also have a diagnostic code stored in the computer indicating what the fault is. I would suggest having a professional from YourMechanic come to your location to take a look at the vehicle to determine what ma be causing this.

My vehicle won't accelerate, then it will?
Hi Dennis. Assuming, the check engine light is not coming on, leads me to believe the ECM (engine control module)/computer is not recognizing the fault.
