Solution
1. Preparation
  • Gather tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, and multimeter.
  • Ensure the vehicle is parked on a level surface and the engine is cool before starting work.
2. Addressing Diagnostic Codes
  • Connect the OBD-II scanner to the vehicle's diagnostic port.
  • Retrieve and document any error codes.
  • Research codes for specific repairs; clear codes if repairs are made.
3. Fuel System Inspection
  • Connect the fuel pressure gauge to the fuel rail.
  • Start the engine and monitor the pressure; it should match manufacturer specifications.
  • If pressure is low, inspect the fuel pump and fuel filter for blockages or failures. Replace if necessary.
4. Air Filter Replacement
  • Open the hood and locate the air filter housing.
  • Remove screws or clips securing the housing and take out the old air filter.
  • Install a new air filter, ensuring it fits snugly in the housing.
5. Spark Plug Replacement
  • Disconnect the battery to prevent electrical shorts.
  • Remove the ignition coil or spark plug wires.
  • Use a socket set to remove old spark plugs; inspect them for wear.
  • Install new spark plugs, tightening to manufacturer-recommended torque specifications.
6. Exhaust System Inspection
  • Visually inspect the exhaust system for any signs of damage or leaks.
  • Use a soapy water solution to check for leaks in exhaust joints.
  • Repair or replace any damaged components as needed.
