Solution
1. Preparation
  • Gather tools and parts: OBD-II scanner, socket set, multimeter, torque wrench.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Address Error Codes
  • Connect the OBD-II scanner and retrieve error codes.
  • Research and document the codes for further analysis.
3. Inspect and Replace Components

A. Gas Cap

  • Check for cracks or damage; replace if necessary.

B. Ignition System

  • Remove spark plugs using a socket set.
  • Inspect for wear; replace if they are worn out (recommended gap: 0.7-0.8 mm).
  • Check ignition coils for proper operation with a multimeter (primary resistance: 0.4-2.0 ohms).

C. Vacuum Leaks

  • Visually inspect hoses for cracks or disconnections.
  • Use a smoke machine or carburetor cleaner to detect leaks; repair or replace as needed.

D. Fuel System

  • Connect a fuel pressure gauge to the fuel rail; ensure pressure matches manufacturer specifications (usually 3.0-4.0 bar).
  • Replace fuel filter if clogged.

E. Exhaust System

  • Visually inspect for holes or rust.
  • Use a back pressure gauge to test the catalytic converter; replace if needed.
4. Reassemble and Test
  • Reconnect all components and ensure all connections are tight.
  • Reconnect the negative battery terminal and clear error codes with the OBD-II scanner.
  • Start the engine and allow it to reach operating temperature.
