Tools Required:

OBD-II scanner
Fuel pressure gauge
Socket set
Multimeter
Screwdrivers
Torque wrench

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and visually inspect it for dirt and debris.
- If dirty, clean it with compressed air or replace it with a new one.
Reinstall the air filter and housing cover, ensuring a tight seal.

3. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reassemble the air intake duct securely.

4. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter along the fuel line.
Use a wrench to disconnect the fuel lines (be cautious of fuel spillage).
Replace the old fuel filter with a new one, ensuring proper orientation and secure connections.

5. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable) with a socket set.
Disconnect the wiring harness from the ignition coils and remove them.
Use a spark plug socket to remove the spark plugs.
Inspect for wear; replace with OEM specifications if necessary.
Reinstall the spark plugs and ignition coils, ensuring they are torqued to manufacturer specifications.
