Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before starting any work.

2. Replace Spark Plug

Remove the engine cover if applicable.
Disconnect the ignition coil connector from the spark plug.
Remove the ignition coil using a socket set.
Unscrew the spark plug using a spark plug socket.
Install a new spark plug, ensuring it is gapped correctly (refer to specifications).
Reinstall the ignition coil and reconnect the electrical connector.

3. Inspect and Replace Ignition Coil (if necessary)

If the ignition coil appeared damaged, remove it as described above.
Replace it with a new ignition coil compatible with the vehicle.
Reattach the coil to the spark plug and reconnect the electrical connector.

4. Inspect and Clean Fuel Injector

Remove the fuel rail to access the fuel injector for cylinder 1.
Carefully remove the injector from the rail.
Clean the injector using a proper cleaning solution or replace it with a new one if damaged.
Reinstall the injector and fuel rail, ensuring all connections are secure.

5. Perform Compression Test (if necessary)

Remove the spark plug from cylinder 1.
Insert a compression gauge into the spark plug hole.
Crank the engine a few times to get a reading.
Compare the reading with specifications; replace the engine if compression is low.
