1. Preparation

• Gather tools and parts required.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery to avoid any electrical shorts.

Tools Required:

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

2. Inspect Ignition System

• Remove the engine cover if necessary.
• Check the spark plugs for wear or damage.
  • Sub-step: Replace spark plugs if worn (Torque to manufacturer specifications).
• Inspect ignition coils for proper operation.
  • Sub-step: Replace any faulty ignition coils.

3. Check for Vacuum Leaks

• Visually inspect all vacuum hoses for cracks or disconnections.
