Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shocks.

2. Inspect Fuel System

Sub-steps:
1. Visually inspect the fuel lines for cracks, corrosion, or leaks.
2. Check the fuel injectors for proper operation and signs of leaking.
3. If any leaks are found, replace the damaged components.
Tools Required: Wrench set, fuel line disconnect tool.
Safety Warnings: Ensure that any fuel leaks are cleaned up immediately to avoid fire hazards.

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coils or spark plug wires.
2. Unscrew and remove the old spark plugs using a socket wrench.
3. Check the gap on the new spark plugs and adjust as needed.
4. Install the new spark plugs and reconnect ignition components.
Tools Required: Socket set, torque wrench.
Safety Warnings: Allow the engine to cool before working on the ignition system.

4. Adjust Air-Fuel Mixture

Sub-steps:
1. Use a scan tool to monitor the air-fuel ratio.
2. If the mixture is too rich, investigate the mass airflow sensor (MAF) and replace if faulty.
3. Clean the MAF sensor with appropriate cleaner.
Tools Required: Scan tool, MAF cleaner.
Safety Warnings: Disconnect the battery before working on electrical components.
