Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, throttle body cleaner, multimeter.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before working on any components.

2. Address Fault Codes

Use the OBD-II scanner to retrieve and document error codes.
Clear the codes and perform a test drive to see if they reappear. If so, focus on those specific issues first.

3. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body and clean with a soft cloth or brush.
Reinstall the air intake duct and reconnect any sensors or hoses.

4. Replace Spark Plugs

Remove the ignition coil(s) using a socket set.
Extract the old spark plugs using a spark plug socket.
Inspect and replace with new spark plugs, ensuring correct gap settings as per manufacturer specifications.
Reinstall ignition coils.

5. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter and check for clogs or leaks.
If it is clogged, replace it with a new filter as per the service manual instructions.

6. Inspect and Test MAF Sensor

Disconnect the MAF sensor connector and remove the sensor from the intake.
Clean the sensor with MAF cleaner and let it dry.
Reinstall the sensor and reconnect the wiring harness.

7. Test Drive

Reconnect the battery terminal and start the vehicle.
Conduct a test drive to ensure the hesitation issue is resolved.
