Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Spark Plug

• Remove the engine cover if necessary.
• Locate cylinder 2 spark plug (refer to service manual for location).
• Use a spark plug socket to remove the spark plug.
• Inspect the plug for deposits or damage; replace if necessary.
• Torque the new spark plug to the manufacturer's specifications (usually around 13-15 lb-ft).

3. Inspect and Replace Ignition Coil

• After removing the spark plug, detach the ignition coil for cylinder 2.
• Inspect the ignition coil for cracks or corrosion; replace if necessary.
• Reinstall the ignition coil and ensure it's seated properly.

4. Check and Clean Fuel Injector

• Locate the fuel injector for cylinder 2 (check service manual for location).
• Disconnect the electrical connector and fuel line (use caution as fuel may spill).
• Remove the fuel injector using the appropriate tool.
• Clean the injector using an ultrasonic cleaner or replace it if faulty.
• Reinstall the fuel injector and reconnect the fuel line and electrical connector.

5. Test for Vacuum Leaks

• Start the engine and use a smoke machine or carburetor cleaner to detect vacuum leaks around intake manifold and vacuum hoses.
• Repair any leaks found to ensure proper air-fuel mixture.
