Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.

Tools Required:

• OBD-II scanner
• Socket set
• Torque wrench
• Multimeter
• Fuel pressure gauge

2. Address Ignition System

1. Remove engine cover if applicable.
2. Disconnect the wiring harness from each ignition coil.
3. Remove the ignition coils using a socket set.
4. Inspect the spark plugs; replace them if worn or fouled.
