Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Disconnect the ignition coils by removing the connector clips.
3. Remove the ignition coils using a socket wrench.
4. Unscrew the old spark plugs using a spark plug socket.
5. Inspect the old plugs for wear; replace with new plugs if necessary (use OEM or equivalent).
6. Install new spark plugs, ensuring they are torqued to manufacturer specifications (typically around 15 ft-lbs).
7. Reinstall the ignition coils and connect the wiring harness.

3. Check and Replace Ignition Coils (if necessary)

Sub-steps:
1. If any ignition coils showed signs of failure, remove them as outlined in the previous section.
2. Install new ignition coils, ensuring they are seated correctly.
3. Reconnect the wiring harness to each coil.

4. Clean Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Spray throttle body cleaner onto a clean cloth or directly into the throttle body.
3. Use a soft brush or cloth to clean the throttle plate and surrounding area carefully.
4. Reattach the air intake duct securely.

5. Check Fuel System

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the 'ON' position without starting the engine and observe the fuel pressure reading.
3. If the pressure is below specifications (check the service manual for exact values), consider replacing the fuel filter and testing the fuel pump.
