Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery to ensure safety during electrical work.

2. Clean or Replace Air Filter

Remove the air filter housing cover.
Take out the air filter and inspect for dirt and damage.
If dirty, clean the filter if reusable, or replace it with a new one.
Reassemble the air filter housing.

3. Inspect and Clean Throttle Body

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft cloth to clean the throttle plate and bore.
Reinstall the throttle body and torque to manufacturer's specifications.

4. Check and Replace Spark Plugs

Remove the ignition coil covers.
Take out spark plugs using a socket and ratchet.
Inspect each spark plug for wear and deposits; replace if necessary.
Reinstall new or cleaned spark plugs and the ignition coil covers.

5. Test and Clean MAF Sensor

Disconnect the MAF sensor connector.
Remove the MAF sensor from the intake duct.
Spray MAF cleaner on the sensing element, avoiding contact with other components.
Reinstall the MAF sensor and reconnect the electrical connector.
