asked by on

Hello there, many different parts can cause the vehicle to run weakly. It would most likely be a misfire condition, spark plug wire, fuel pump, low fuel pressure, or an oxygen sensor. A qualified technician, such as one from YourMechanic, will be able to inspect your car’s loss of power and perform any repairs required.
