Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Allow the engine to cool if it has been running.

2. Inspect and Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Using a throttle body cleaner, spray inside the throttle body while opening the throttle plate manually.
Wipe clean with a lint-free cloth, ensuring there are no carbon deposits remaining.
Reattach the air intake duct securely.

3. Replace Spark Plugs and Ignition Coils (if necessary)

Remove the engine cover (if equipped) to access the ignition components.
Disconnect the ignition coil connectors.
Remove the ignition coils using a socket wrench.
Replace spark plugs using a spark plug socket, ensuring the gap is set to manufacturer specifications.
Reinstall the ignition coils and reconnect the connectors.

4. Test and Replace the MAF Sensor (if faulty)

Disconnect the MAF sensor connector and remove it from the air intake.
Inspect the sensor for dirt; if dirty, clean it using MAF sensor cleaner.
If cleaning does not resolve issues, replace the MAF sensor with a new unit.
Reconnect the MAF sensor and ensure it's secured.

5. Inspect Fuel System

Use a fuel pressure gauge to check the fuel pressure at the rail.
If pressure is low, inspect the fuel pump, filter, and lines for blockages or leaks.
Replace any faulty components as necessary.

6. Reconnect Battery

Once all repairs are complete, reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes to check for stability.
