Q: My car does not want to gain any type of speed

asked by on

When I drive my car, it doesn't gain any type of speed. Even if press the gas pedal all the way down. What can possibly be wrong with my car?
My car has an automatic transmission.

Hi there. A lack of acceleration could be the result of several possibilities and requires proper diagnoses. Low fuel pressure, caused by a faulty fuel pump, a faulty fuel pressure regulator, a plugged fuel filter. A restricted exhaust system, plugged catalytic converter. A faulty MAF (mass airflow) sensor, incorrectly calculating the incoming air to the engine. Assuming, the check engine light is not on, leads me to believe the PCM (powertrain control module)/computer is not recognizing the fault. I recommend having your vehicle's doesn't gain speed be diagnosed and repaired by a certified technician, such as one from YourMechanic.
