Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Check and Replace Spark Plugs

Sub-steps:
1. Disconnect the battery to prevent electrical shorts.
2. Remove the engine cover (if applicable) using a socket set.
3. Remove the spark plug wires or ignition coils, noting their positions.
4. Use a spark plug socket to remove the spark plugs.
5. Inspect the spark plugs for wear or fouling and replace them if necessary with OEM parts.
6. Torque the new spark plugs to the manufacturer's specifications (typically around 13-15 lb-ft).
7. Reinstall the ignition coils and spark plug wires.

3. Clean the Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft cloth or brush to clean the throttle plate and surrounding areas.
3. Allow the cleaner to dry, then reattach the air intake duct securely.

4. Inspect and Replace Air Filter

Sub-steps:
1. Locate the air filter housing and unclip or unscrew it.
2. Remove the old air filter and inspect for dirt or damage.
3. Install a new, OEM air filter ensuring a proper fit.
4. Reattach the air filter housing cover.

5. Test and Replace Mass Airflow Sensor (if necessary)

Sub-steps:
1. Disconnect the electrical connector from the MAF sensor.
2. Remove the MAF sensor from the intake duct.
3. Inspect the sensor for contamination; clean it with MAF cleaner if dirty.
4. If cleaning does not resolve issues, install a new OEM MAF sensor.
5. Reconnect the electrical connector.
