Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace Spark Plug

• Remove the ignition coil and spark plug from cylinder 2.
• Inspect the spark plug for wear, carbon buildup, or damage.
• If necessary, replace the spark plug with a new one (OEM recommended).
• Torque the spark plug to the manufacturer’s specifications (typically around 13-16 ft-lbs).

3. Check and Replace Ignition Coil

• Test the ignition coil for cylinder 2 using a multimeter to check resistance.
• If defective, replace the ignition coil with a new one (OEM recommended).
• Reinstall the ignition coil and ensure it is seated properly.

4. Inspect and Replace Fuel Injector

• Remove the fuel injector for cylinder 2.
• Check for clogging or damage; clean the injector if possible or replace it with a new one if necessary.
• Reinstall the injector and ensure proper connections.

5. Perform a Compression Test

• If issues persist, conduct a compression test on cylinder 2.
• Compare the reading to the specifications outlined in the service manual.
• If compression is low, further investigation into piston rings or valves may be needed.
