Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to prevent electrical shocks.
2. Inspect and Replace Spark Plugs
  • Remove the ignition coil covers.
  • Use a socket set to remove spark plugs.
  • Inspect for wear (electrode condition) and replace with OEM-spec spark plugs if damaged.
  • Reinstall the spark plugs and connect the ignition coils.
3. Clean the Throttle Body
  • Remove the air intake duct to access the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
  • Ensure the throttle body operates smoothly when opened and closed.
4. Test and Replace the Engine Coolant Temperature Sensor
  • Locate the coolant temperature sensor and disconnect the electrical connector.
  • Remove the sensor using an appropriate tool.
  • Install a new sensor and reconnect the electrical connector.
5. Inspect and Repair Fuel System
  • Connect a fuel pressure gauge to the fuel rail.
  • Start the engine and monitor fuel pressure; it should be within the manufacturer’s specifications.
  • If fuel pressure is low, inspect the fuel filter, pump, and lines for clogs or damage. Replace any faulty components.
