Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety.
  • Allow the engine to cool before working on it.
2. Inspect and Clean Air Intake System
  • Remove the air filter and inspect it for dirt and debris.
    • If dirty, replace it with a new air filter.
  • Clean the throttle body using throttle body cleaner.
    • Spray cleaner into the throttle body while opening the throttle plate manually.
3. Check Fuel System
  • Connect the fuel pressure gauge to the fuel rail.
  • Turn the ignition key to the "on" position (do not start) to check for fuel pressure.
    • Compare the reading with manufacturer specifications (typically 30-40 PSI for F-150).
  • If pressure is low, check the fuel pump and replace if necessary.
4. Inspect Throttle Position Sensor (TPS)
  • Locate the TPS on the throttle body.
  • Use a multimeter to check voltage output while moving the throttle.
    • Ensure it provides a smooth and consistent voltage range (typically 0.5V to 4.5V).
  • Replace the TPS if readings are outside the normal range.
5. Examine Spark Plugs and Ignition Coils
  • Remove the spark plugs for inspection.
    • Replace if they show signs of wear or fouling.
  • Test the ignition coils with a multimeter for proper resistance.
    • Replace any faulty coils.
