Solution
1. Preparation
  • Gather tools and parts required for the repair.
  • Disconnect the negative battery cable to prevent electrical shorts.
2. Inspect and Clean Air Intake System
  • Remove the air filter and inspect it for dirt or damage; replace if necessary.
  • Check the intake manifold for carbon buildup and clean using an appropriate throttle body cleaner.
3. Fuel System Inspection
  • Disconnect the fuel pump relay and use a fuel pressure gauge to check the fuel pressure at the fuel rail.
    • Expected Pressure: Refer to manufacturer specifications (typically between 50-60 psi).
  • If pressure is low, replace the fuel filter and/or fuel pump as needed.
4. Ignition System Service
  • Remove spark plugs using a socket wrench and inspect for wear or carbon deposits.
  • Replace spark plugs if they are worn beyond manufacturer specifications (usually every 30,000-60,000 miles).
  • Check ignition coils for proper operation; replace any that show signs of failure.
5. Throttle Position Sensor (TPS) Check
  • Locate the TPS on the throttle body and disconnect the electrical connector.
  • Use a multimeter to measure the voltage output; compare with manufacturer specifications.
  • If out of range, replace the TPS.
6. Reassemble and Test
  • Reconnect all components, ensuring all electrical connectors are secure.
  • Reconnect the battery and clear any error codes from the OBD-II scanner.
  • Start the engine and perform a test drive to confirm the repair.
