-Fuel Efficiency: Ensure that your car has enough fuel and the fuel is flowing correctly.
-Air Filter: A clogged air filter can restrict airflow to the engine, reducing performance.
-Spark Plugs: Worn-out spark plugs can cause misfires, leading to reduced engine performance.
-Fuel Injectors: Malfunctioning fuel injectors can affect the fuel mixture, causing performance problems.
-Transmission: A slipping transmission can cause the engine to rev high without the car gaining speed.
-Vacuum Leaks: Vacuum leaks can affect engine performance by allowing unmeasured air into the engine.
-Oxygen Sensors: Faulty oxygen sensors can provide incorrect information to the engine's computer, impacting fuel efficiency and performance.
-EGR Valve: A malfunctioning EGR valve can cause performance issues by affecting the exhaust gas recirculation.
-Turbocharger or Supercharger (if equipped): Check if the turbocharger or supercharger is functioning correctly if your car has one.
-Electrical Issues: Check for any electrical issues that may affect the proper functioning of the engine.
-Computer Problems: Issues with the car's computer (Engine Control Unit) can also impact engine performance.
