Air Filter Clogged: A dirty air filter can limit the airflow to the engine, causing a decrease in power. Regularly inspect and replace the air filter.
EGR (Exhaust Gas Recirculation) Valve: A faulty EGR valve can disrupt the air-fuel mixture, resulting in power loss. Clean the valve or have it replaced if necessary.
Turbocharger Issues: A faulty turbocharger can affect the air pressure supplied to the engine, leading to reduced power output. Check for turbocharger leaks or failures and repair or replace as required.
Fuel Injector Issues: Faulty fuel injectors can disrupt the fuel delivery to the engine, causing a loss of power. Have the injectors inspected and replaced if needed.
Vacuum Leak: A vacuum leak in the intake system can cause the engine to run lean and lose power. Inspect the hoses and connections for any leaks and repair them accordingly.
Faulty Sensors: A malfunctioning sensor, such as the oxygen sensor, mass airflow sensor, or throttle position sensor, can provide incorrect information to the engine's control unit, resulting in power loss. Diagnose and replace the faulty sensors.
