Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to prevent electrical shorts.

2. Clean or Replace the Throttle Body

Remove the air intake duct connected to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
If the throttle body is damaged, replace it with a new one.

3. Inspect and Replace Fuel Filter

Locate the fuel filter, which is typically near the fuel tank.
Use the appropriate tools to disconnect the fuel lines, ensuring to relieve fuel pressure beforehand.
Replace the old fuel filter with a new one, using new clamps if necessary.

4. Check and Replace Spark Plugs

Remove the ignition coil or spark plug wires from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect for wear or carbon deposits; replace with OEM or equivalent spark plugs.
Reinstall the ignition coils or wires securely.

5. Test and Replace MAF Sensor (if needed)

Disconnect the electrical connector from the MAF sensor.
Remove the MAF sensor from the air intake tube.
Inspect for contamination; clean with MAF sensor cleaner or replace if faulty.
Reinstall the MAF sensor and reconnect the electrical connector.
