Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Replace Spark Plugs

Locate the spark plug wires or ignition coils and remove them carefully.
Use a spark plug socket to remove the old spark plugs.
Inspect the old spark plugs for wear and replace them with new ones, ensuring they are gapped according to specifications.
Torque the new spark plugs to the manufacturer's specified value (usually around 13-15 ft-lbs).

3. Test and Replace Ignition Coils

Disconnect the ignition coils and remove them from the engine.
Test each coil with a multimeter to ensure they are within the correct resistance range.
Replace any faulty ignition coils with new ones, ensuring they are properly seated and connected.

4. Inspect and Clean Fuel Injectors

Remove the fuel rail and injectors from the engine.
Use a fuel injector cleaning kit to clean the injectors. Alternatively, replace them if they are beyond cleaning.
Reinstall the injectors and ensure proper sealing and connections.

5. Check Air Filter and Intake

Remove the air filter and inspect it for dirt and obstructions.
Replace the air filter if it is dirty or clogged.
Check the intake system for any blockages or leaks.

6. Inspect Vacuum Hoses

Visually inspect all vacuum hoses for cracks, leaks, or disconnections.
Replace any damaged hoses with new ones and ensure all connections are tight.
