I potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or droppings.

Gasoline from less-than-reputable sources that has been improperly stored or transported is more likely to comprise dissentious droppings that could brand its way through the fuel lines and to the injectors -- ruining them.

The problem may also be with one of the components, like the computer or the ignition coils, that supply power to the spark plugs

i. Bad Crankshaft Position Sensor

Not simply does the engine in your motorcar need a spark to begin combustion, that spark has to take place at the exact right moment. Too late or besides early and the air/fuel mixture won't entirely combust, reducing performance and potentially failing to get-go the engine entirely.

Information technology's this sensor that tells your engine'south estimator the position of all the valves and pistons at any given moment.
