Solution
1. Preparation
  • Gather tools and parts required for repair.
  • Disconnect the battery to ensure safety while working on the vehicle.
2. Fuel System Check
  1. Testing Fuel Pressure

    • Connect a fuel pressure gauge to the fuel rail.
    • Turn the ignition to the "ON" position without starting the engine and note the pressure reading. It should match the specification in the service manual (typically around 58-65 psi).
    • If pressure is low, inspect the fuel pump and filter for issues.
  2. Replace Fuel Filter (if necessary)

    • Locate the fuel filter (under the vehicle near the tank).
    • Use a wrench to disconnect the fuel lines (be cautious of fuel spillage).
    • Remove the old filter and install the new one, ensuring proper orientation.
3. Ignition System Maintenance
  1. Inspect and Replace Spark Plugs
    • Remove the spark plug wires carefully.
    • Use a spark plug socket to remove the spark plugs.
    • Check for wear and gap; replace if they are fouled or out of specification.
    • Install new spark plugs and reconnect the wires.
4. Air Intake Inspection
  • Remove the air intake duct and inspect the air filter. Replace it if dirty.
  • Check for any obstructions in the intake manifold.
5. Engine Coolant Temperature Sensor
  1. Inspect Sensor
    • Locate the engine coolant temperature sensor (usually near the thermostat housing).
    • Disconnect the sensor's electrical connector and check resistance with a multimeter.
    • If resistance is out of specification, replace the sensor.
6. Reassemble and Test
  • Reconnect the battery.
  • Start the vehicle and check for a smooth idle and absence of warning lights.
