⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Allow the engine to cool completely before inspecting components.

Symptoms

•Engine sputtering during acceleration
•Unusual engine noises (e.g., knocking or pinging)
•Decreased throttle response
•Check engine light illuminated
•Poor fuel economy
•Rough idle when stationary

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any stored trouble codes.
2
Inspect the air intake system for blockages or leaks in the air filter and intake ducts.

Solution

1. Preparation

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

2. Inspect and Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brushes, socket set.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the interior of the throttle body thoroughly.
Reinstall the air intake duct securely.

3. Replace Fuel Filter

Tools Required: Wrench set, new fuel filter.
Locate the fuel filter, usually found along the fuel line under the vehicle.
Depressurize the fuel system by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the old fuel filter using the wrench and replace it with a new one, ensuring proper orientation.
Reconnect the fuel pump fuse and check for leaks.

4. Inspect and Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench.
Remove the ignition coils to access the spark plugs.
Use a spark plug socket to remove each spark plug, inspecting them for wear or damage.
Replace with new spark plugs, ensuring they are torqued to the manufacturer’s specifications.

5. MAF Sensor Cleaning

Tools Required: MAF sensor cleaner.
Locate the MAF sensor in the air intake system.
Carefully remove the sensor, being cautious not to damage it.
Spray the MAF sensor with MAF cleaner and allow it to dry completely before reinstalling.
