Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts or shocks.

2. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reinstall the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (usually near the fuel tank or along the fuel line).
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter, being cautious of residual fuel.
Remove the old fuel filter and install the new one, ensuring correct orientation.
Reconnect fuel lines and fuse.

4. Inspect and Replace Spark Plugs

Remove the ignition coil covers if applicable.
Use a socket set to remove the spark plugs, inspecting them for wear or carbon buildup.
Replace with OEM spark plugs, ensuring proper torque (typically around 13 lb-ft).
Reinstall ignition coils and covers.

5. Clean or Replace MAF Sensor

Disconnect the MAF sensor connector.
Remove the MAF sensor from the intake manifold.
Clean the sensor with MAF cleaner or replace if damaged.
Reinstall the MAF sensor and reconnect the connector.
