Q: What would cause a vehicle to cut off going down the road?

asked by on January 27, 2018

My car keeps cutting off driving down the road. Sometimes I have to keep my foot near the brake and on the gas at the same time to keep from cutting off. We replaced the engine crank sensor, idling control valve, fuel filter and it still keeps doing it . I have to pull off the side of the road and try to start it back.

My car has 150000 miles.
My car has an automatic transmission.
