Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before beginning work.

2. Inspect and Replace Spark Plugs

Remove the ignition coil cover using a socket set.
Unplug the ignition coils and remove them using a socket.
Extract the old spark plugs using a spark plug socket.
Inspect the old spark plugs for wear; replace if necessary with OEM parts.
Torque new spark plugs to the manufacturer’s specifications (usually around 13-15 ft-lbs).
Reinstall the ignition coils and cover.

3. Check Fuel System

Verify the fuel pump operation by listening for the pump sound upon turning the ignition on.
If necessary, replace the fuel filter (if equipped) and inspect fuel lines for leaks.
Test fuel pressure using a fuel pressure gauge and ensure it meets manufacturer specifications.

4. Inspect Air Intake

Remove the air intake duct and inspect the air filter for dirt and debris.
Clean or replace the air filter as necessary.
Inspect the throttle body for carbon buildup; clean it if necessary using throttle body cleaner.

5. Check Battery and Connections

Inspect the battery terminals for corrosion and clean if needed.
Test the battery voltage with a multimeter; replace if voltage is below 12.4 volts.
Ensure all electrical connections to the battery and ground are secure.

6. Verify Engine Coolant Temperature Sensor

Locate the coolant temperature sensor and check for signs of damage.
Use a multimeter to test the resistance of the sensor against manufacturer specifications.
Replace the sensor if it is out of specification.
