Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Ignition Components

• Tools Required: Socket set, torque wrench, spark plug socket, ignition coil puller.
• Remove the engine cover if applicable.
• Remove the ignition coil from cylinder 2:
  1. Disconnect the electrical connector from the ignition coil.
  2. Remove the mounting bolt(s) securing the ignition coil.
  3. Carefully pull the ignition coil out of the spark plug well.
• Remove and inspect the spark plug:
  1. Use a spark plug socket to unscrew the spark plug from cylinder 2.
  2. Check the spark plug for wear, carbon buildup, or damage.
  3. Replace with a new spark plug if necessary, ensuring it is gapped according to manufacturer specifications (typically 0.028-0.031 inches).
• Reinstall the ignition coil or replace it if found to be faulty.

3. Inspect and Replace Fuel Injector

• Tools Required: Fuel injector removal tool, torque wrench.
• Remove the fuel rail if necessary to access the fuel injector for cylinder 2:
  1. Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
  2. Disconnect the fuel line from the rail using a special tool, if required.
  3. Remove the bolts securing the fuel rail and gently lift it to access the injector.
• Remove the fuel injector:
  1. Disconnect the electrical connector from the injector.
  2. Carefully pull the injector out of its seat.
• Install a new fuel injector, ensuring proper O-ring lubrication with clean engine oil.

4. Reassemble and Test

• Reinstall the fuel rail and secure it with bolts, ensuring they are torqued to manufacturer specifications.
• Reconnect the fuel line and ignition coil.
• Reconnect the battery.
• Start the engine and allow it to idle.
