Solution

1. Preparation

Gather necessary tools and materials.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Spark Plug

Remove the engine cover if applicable.
Remove the spark plug for cylinder 1 using a spark plug socket.
Inspect the spark plug for wear or damage. If necessary, replace it with a new one (OEM recommended).
- Torque Specification: Tighten to manufacturer’s specification (typically 13-15 lb-ft).

3. Test and Replace Ignition Coil

Disconnect the ignition coil connector for cylinder 1.
Remove the ignition coil using a socket or wrench.
Test the ignition coil with a multimeter to ensure it is operating correctly; replace if faulty.
Install a new ignition coil, ensuring it is secure and reconnect the electrical connector.

4. Check and Clean Fuel Injector

If the injector is suspected to be faulty, remove it from the fuel rail.
Clean the injector or replace it if it is clogged or damaged.
Reinstall the fuel injector and ensure it is properly seated.

5. Conduct Compression Test

If all previous components are functioning, perform a compression test on cylinder 1.
If compression is low, further diagnosis may be necessary for internal engine issues (e.g., valve problems, head gasket failure).
