Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to avoid electrical shorts.
Allow the engine to cool down before starting work.

2. Replace Spark Plug

Tools Required: Socket set (including spark plug socket), torque wrench
Remove the ignition coil from cylinder 1 by unscrewing the bolts and disconnecting the electrical connector.
Remove the spark plug using the spark plug socket and ratchet.
Inspect the old spark plug for wear; replace with a new spark plug (ensure correct gap setting).
Install the new spark plug and torque it to the manufacturer’s specification (typically 12-15 lb-ft).
Reattach the ignition coil and ensure the connector is secured.

3. Replace Ignition Coil (if necessary)

Tools Required: Socket set, torque wrench
If the ignition coil appears damaged or malfunctioning, remove it and replace it with a new one.
Torque the ignition coil bolts to the specified torque (usually around 7-10 lb-ft).

4. Check and Replace Fuel Injector (if necessary)

Tools Required: Fuel injector removal tool, socket set
If the fuel injector is malfunctioning, remove it by disconnecting the electrical connector and fuel line.
Replace it with a new fuel injector, ensuring it is seated properly.
Reconnect the fuel line and electrical connector securely.

5. Reassemble and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes.
Monitor for any unusual sounds or issues.
