Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Spark Plugs

• Remove the ignition coil cover.
• Disconnect ignition coils and remove them using a socket set.
• Extract the spark plugs using a spark plug socket; inspect for wear or carbon buildup.
• Replace old spark plugs with OEM recommended plugs, ensuring proper gap specifications.
• Reinstall ignition coils and cover.

3. Test and Replace Ignition Coils (if required)

• Use a multimeter to test each ignition coil's resistance according to manufacturer specifications.
• If a coil is out of spec, remove the faulty coil and replace it with a new one.
• Reinstall the ignition coil securely and reconnect the wiring harness.

4. Inspect and Clean Fuel Injectors

• Remove the fuel rail if necessary to access injectors.
• Inspect injectors for clogs; clean using a fuel injector cleaning kit or replace if damaged.
