Hello. Without further detail as to the specific make and model of your car, it may be difficult to diagnose. However, most cars have a "safe mode" or limp mode" that the transmission ECU will enable when either the transmission ECU or the main ECU detects a critical problem with the car. This is done to prevent further damage and to protect the safety of the passengers in the car. I would recommend having an expert from YourMechanic come to your home to diagnose the poor acceleration and proceed with the proper repairs.
