Solution
1. Preparation
  • Gather the necessary tools and parts.
  • Disconnect the battery before working on any electrical components.
  • Ensure the engine is cool to prevent burns.
2. Address Fuel System Issues
  1. If the DTC indicates fuel system problems, check fuel pressure with a fuel pressure gauge.
    • Tool Required: Fuel pressure gauge.
    • Sub-step: If pressure is low, inspect the fuel pump and fuel filter for blockages or failures.
  2. Inspect and clean or replace fuel injectors if they are clogged or malfunctioning.
3. Repair Vacuum Leaks
  1. Conduct a visual inspection of all hoses connected to the intake manifold.
  2. Use a smoke machine or spray soapy water to detect any leaks.
  3. Replace any damaged hoses or gaskets that may be causing vacuum leaks.
4. Inspect Ignition System
  1. Remove spark plugs for inspection; replace them if they show signs of wear or fouling.
  2. Check ignition coils for proper function; replace any that are defective.
    • Torque value for spark plugs: 13 lb-ft (17.6 Nm).
5. Examine Exhaust System
  1. Inspect the catalytic converter for blockages or damage; replace if necessary.
  2. Check O2 sensors for proper operation; replace any faulty sensors.
