Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Clean Air Intake System

Remove the air filter and inspect it for dirt or damage.
Clean the air intake duct and throttle body using throttle body cleaner.
Reinstall the air filter and ensure all connections are secure.

3. Check and Replace Fuel Components

Use a fuel pressure gauge to check if the fuel pressure is within manufacturer specifications.
If low, inspect the fuel pump and fuel filter. Replace the fuel filter if clogged.
If necessary, replace the fuel pump following these sub-steps:
1. Remove the fuel pump relay and fuse.
2. Disconnect the fuel lines (use safety goggles due to fuel spillage).
3. Remove the fuel pump assembly from the fuel tank.
4. Install the new fuel pump and reassemble the components.

4. Inspect Ignition System

Remove and inspect spark plugs for wear and carbon buildup; replace if necessary.
Test ignition coils using a multimeter to ensure proper resistance.
Replace any faulty ignition coils and reconnect wiring securely.

5. Reconnect and Test

Reconnect the battery.
Start the engine and monitor for any abnormal sounds or warning lights.
