Q: Keeps dying and won't go past 20

asked by on

What could cause it to die and knock like hell

My car has 185187 miles.
My car has an automatic transmission.

A few different things can cause the engine to knock like this. The most likely would be low fuel pressure, the wrong octane gasoline, or an extreme misfire. I would not drive a vehicle that is knocking this badly as it can cause damage to the vehicle if use continues. A qualified technician, such as one from YourMechanic, will be able to diagnose your stalling and knocking issue and perform any repairs required.
