5. Torque the bolts to the manufacturer's specifications.

3. Check and Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver
Sub-steps:
1. Locate the throttle body, typically found between the air intake and engine.
2. Disconnect the throttle body electrical connector and intake duct.
3. Use a throttle body cleaner to spray the inside of the throttle body.
4. Wipe clean with a soft cloth, ensuring no debris remains.
5. Reconnect the intake duct and electrical connector.

4. Inspect and Replace Spark Plugs and Ignition Coils

Tools Required: Socket set, torque wrench, spark plug socket
Sub-steps:
1. Remove the engine cover if necessary to access the spark plugs.
2. Disconnect the ignition coil connectors and remove the coils using a socket set.
3. Use a spark plug socket to carefully remove the old spark plugs.
