Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical issues during repairs.

2. Fuel System Inspection

Remove the fuel pump relay from the fuse box.
Use a fuel pressure gauge to test the fuel system; it should read between 40-50 psi.
- Tools Required: Fuel pressure gauge, socket set.
If the pressure is low, check the fuel filter for clogs and replace it if necessary.
Reconnect the fuel pump relay once testing is complete.

3. Air Intake System Cleaning

Remove the air intake duct to access the throttle body.
Clean the throttle body using throttle body cleaner and a soft cloth to remove carbon deposits.
- Tools Required: Throttle body cleaner, soft cloth, screwdriver.
Reinstall the air intake duct securely.

4. Ignition System Check

Remove the ignition coils and inspect the spark plugs for wear or carbon buildup.
Replace spark plugs if they are worn or fouled.
- Torque Specification: 13 lb-ft for spark plug installation.
Reinstall the ignition coils and ensure they are seated properly.

5. Coolant Temperature Sensor Inspection

Locate the engine coolant temperature sensor and check its wiring for damage.
Use a multimeter to test the sensor's resistance; it should vary with temperature.
- Tools Required: Multimeter.
Replace the coolant temperature sensor if it shows inconsistent readings.
