Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before starting work.

2. Inspect and Replace Spark Plug

Remove the ignition coil from cylinder 2:
- Use a socket wrench to remove the bolts securing the coil.
- Gently pull the coil out, being careful not to damage the connector.
Remove the spark plug:
- Use a spark plug socket and ratchet to unscrew and remove the spark plug.
Inspect the spark plug for wear or fouling.
Replace with a new spark plug if necessary, torquing to the manufacturer's specifications (typically around 13-15 lb-ft).

3. Inspect and Replace Ignition Coil

If the spark plug is fine, test the ignition coil:
- Use a multimeter to check the primary and secondary resistance according to specs.
Replace the ignition coil if it's defective, ensuring a proper fit and securing the bolts to the specified torque.

4. Check Fuel Injector

Disconnect the fuel injector connector for cylinder 2.
Test the injector with a multimeter, checking for continuity and proper resistance.
Replace the fuel injector if it does not meet specifications.

5. Test Compression

Remove the spark plug from cylinder 2 and install a compression gauge.
Crank the engine and record the compression reading.
Compare the reading to the specifications; if low, further diagnostics are needed for internal engine issues.

6. Reassemble and Clear Codes

Reconnect all components, ensuring secure connections.
Reconnect the negative battery terminal.
Use an OBD-II scanner to clear the P0302 code and perform a test drive.
