Fuel Pump Check
- Use a fuel pressure gauge to measure fuel pressure at the rail.
- Compare readings to manufacturer specifications.
- If pressure is low, replace the fuel pump.
Fuel Filter Replacement
- Locate and remove the fuel filter.
- Replace with a new filter ensuring correct orientation.

3. Inspect Air Intake System

Air Filter Replacement
- Remove the air intake duct.
- Replace the air filter if it is dirty or clogged.
Mass Air Flow Sensor Cleaning
- Disconnect the MAF sensor.
- Use MAF cleaner to gently clean the sensor.
- Reinstall the MAF sensor.

4. Check Ignition System

Spark Plug Inspection
- Remove spark plugs and inspect for wear or carbon buildup.
- Replace any damaged or worn spark plugs with the recommended type.
Ignition Coil Testing
- Use a multimeter to test the resistance of each ignition coil.
- Replace any coils that do not meet specifications.
