* Dirty fuel injectors: Fuel injectors spray fuel into the engine's cylinders. If the fuel injectors are dirty, they can become clogged and prevent the engine from getting the fuel it needs. This can lead to loss of power and decreased fuel efficiency.
* Vacuum leak: A vacuum leak can cause the engine to run lean, which can lead to loss of power and decreased fuel efficiency.
* Faulty spark plugs or wires: Spark plugs and wires are responsible for delivering the spark that ignites the fuel in the engine's cylinders. If the spark plugs or wires are faulty, they can cause the engine to misfire, which can lead to loss of power and decreased fuel efficiency.
* Faulty catalytic converter: The catalytic converter helps to clean up the exhaust gases from the engine. If the catalytic converter is faulty, it can restrict the flow of exhaust gases and cause the engine to lose power and get worse fuel efficiency.
