Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt or blockages.
Install a new air filter, ensuring it is seated properly.
Reattach the air filter housing cover and tighten screws to the manufacturer's torque specifications.

3. Check and Replace Spark Plugs and Ignition Coils

Remove the ignition coil cover using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Inspect spark plugs for wear; replace them if necessary (recommended gap: 0.028 inches).
Install new ignition coils and reconnect them securely.
Reinstall the ignition coil cover.

4. Clean Throttle Body

Remove the throttle body from the intake manifold by loosening the clamps and disconnecting the electrical connector.
Use throttle body cleaner and a soft brush to clean the interior surfaces.
Reinstall the throttle body and reconnect all components.

5. Inspect and Replace MAF Sensor (if necessary)

If MAF sensor testing indicated a fault, disconnect the electrical connector and remove the MAF sensor from the intake.
Install a new MAF sensor and reconnect the electrical connector.
