Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuel Filter

Locate the fuel filter; it may be under the vehicle near the fuel tank.
Use a socket set to remove the filter from the fuel lines.
Replace with a new fuel filter ensuring proper flow direction.
Reconnect the fuel lines securely.

3. Replace Spark Plugs and Ignition Coils

Remove the engine cover if applicable.
Disconnect the ignition coil connectors and remove the bolts using a socket set.
Pull out the ignition coils and inspect them for damage.
Replace spark plugs with new ones, ensuring they are gapped correctly according to manufacturer specifications.
Reinstall ignition coils and connectors.

4. Clean or Replace MAF Sensor

Locate the mass airflow sensor in the intake duct.
Disconnect the electrical connector and remove any screws holding it in place.
If cleaning, use MAF sensor cleaner and a soft brush to clean the sensor; avoid touching the sensor directly.
If replacing, install the new MAF sensor and reconnect the electrical connector.

5. Reconnect Battery and Test

Reconnect the battery terminals and ensure they are tight.
Start the engine and allow it to idle for a few minutes to check for any immediate issues.
