3. Replace any damaged vacuum hoses found during inspection.

4. Inspect Spark Plugs and Ignition Coils

Tools Required: Spark plug socket, torque wrench
Instructions:
1. Remove the engine cover if necessary to access the spark plugs.
2. Use the spark plug socket to remove each spark plug and inspect for wear or fouling.
3. Replace any worn spark plugs with OEM replacements and torque to specifications.
4. Inspect ignition coils for cracks or wear; replace if necessary.

5. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth
Instructions:
