Why does my truck sputter when I accelerate?

Dirty or Failing Spark Plugs – The job of a spark plug is to ignite the fuel in the combustion chamber. Therefore, if one is dirty or faulty, your engine will struggle to start and sputter when you hit the gas. A clogged fuel injector nozzle causes a car engine to shake and struggle to accelerate.

What causes a car to sputter at high rpm?

Car Sputters at High Speeds When your car is traveling at faster speeds a fuel pump needs to supply constant fuel with a stable amount of pressure. If your pump is failing it will struggle to keep up with the demand and cause your vehicle to sputter.

What causes a diesel engine to sputter?

The ignition source of a diesel engine is the heat generated by the compression of the air in the cylinder, rather than a spark as in gasoline engines. If the injector is damaged or dirty, a small amount of fuel can enter the chamber and be ignited, causing a sputter or two after the engine is switched off.
