Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts while working.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt and debris.
Install a new, clean air filter (OEM recommended).
Reassemble the air filter housing and secure it.

3. Fuel System Check

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading.
If pressure is below specifications, replace the fuel pump or fuel filter as needed.
Disconnect the gauge and reassemble any components.

4. Throttle Body Cleaning

Remove the air intake duct from the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and bore.
Ensure that the throttle plate moves freely.
Reattach the air intake duct securely.

5. Ignition System Inspection

Remove the ignition coils from the spark plugs.
Inspect the spark plugs for wear, deposits, or damage; replace if necessary.
Reinstall the ignition coils and ensure proper connections.

6. Exhaust System Inspection

Visually inspect the exhaust system for any signs of damage or blockage.
If a blockage is suspected, consider performing a back pressure test.
Replace any damaged components (e.g., catalytic converter, muffler) if necessary.
