Remove the fuel rail if necessary, ensuring the fuel system is depressurized.
Remove the fuel injectors from the rail.
Clean the injectors using a dedicated injector cleaning solution or replace if damaged.
Reinstall the injectors and fuel rail, ensuring proper sealing.

C. Check Air Intake System

Visually inspect air intake hoses for cracks or loose connections.
Clean the Mass Air Flow (MAF) sensor if present, using MAF cleaner.
Reconnect all hoses and ensure a tight fit.
