Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install the new air filter, ensuring it fits snugly, and reattach the housing cover.

3. Test and Replace Spark Plugs

Remove the ignition coils using a socket set.
Extract the spark plugs with a spark plug socket and inspect for wear.
If necessary, replace the spark plugs with new ones, ensuring the gap is set to manufacturer specifications (usually around 0.044 inches).
Reinstall ignition coils and connectors.

4. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body while opening the throttle plate manually.
Wipe away carbon deposits with a clean cloth.
Reassemble the intake duct securely.

5. Check Fuel System

Attach the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading against manufacturer specifications.
If the pressure is low, check the fuel filter and replace if necessary.

6. Inspect Exhaust System

Visually check for any rust, holes, or blockages in the exhaust pipes and muffler.
If any issues are found, replace the damaged sections of the exhaust system.
