Solution
1. Preparation
  • Gather tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, cleaning solvent, air intake cleaner.
  • Disconnect the battery to ensure safety during repairs.
  • Allow the engine to cool before starting work on any components.
2. Address Codes and Engine Issues
  • Use the OBD-II scanner to retrieve and document any error codes.
  • Clear the error codes, then test drive the vehicle to see if they reappear.
  • If codes indicate specific components (e.g., MAF sensor, fuel injectors), proceed to replace or clean those parts as necessary.
3. Fuel System Inspection and Repair
  • Remove the fuel pump access panel (if applicable) or disconnect the fuel lines (safety: relieve fuel pressure beforehand).
  • Use the fuel pressure gauge to check the pressure; replace the fuel filter if pressure is low.
  • If the pressure is adequate, inspect fuel injectors for clogs or leaks, and clean or replace them as required.
4. Air Intake System Cleaning
  • Remove the air filter and inspect for dirt or blockages; replace if necessary.
  • Clean the throttle body using throttle body cleaner and a soft cloth.
  • Reassemble the air intake system, ensuring all connections are secure.
5. Spark Plug and Ignition System Maintenance
  • Remove spark plugs using a socket and inspect for wear, carbon buildup, or damage.
  • Replace spark plugs if they are worn beyond specifications (check OEM specifications for gap size).
  • Test ignition coils and replace any that are faulty based on manufacturer specifications.
