Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition key to the "ON" position (do not start the engine) and check the fuel pressure reading against manufacturer specifications.
If pressure is low, inspect the fuel pump and filter for issues, and replace as needed.

3. Air Intake Inspection

Tools Required: Screwdriver set, cleaning brush.
Remove the air intake duct to access the throttle body.
Inspect the air filter for dirt and debris; replace if necessary.
Clean the throttle body using throttle body cleaner and a soft brush to remove carbon buildup.

4. Ignition System Check

Tools Required: Spark plug socket, multimeter.
Remove the spark plugs and inspect for wear or fouling; replace if necessary.
Test the ignition coils with a multimeter to ensure they are within specifications; replace faulty coils.

5. Engine Coolant Temperature Sensor

Tools Required: Multimeter.
Locate the engine coolant temperature sensor and disconnect the wiring harness.
Use a multimeter to check resistance values; compare with manufacturer specifications to confirm sensor operation.
Replace the sensor if it is out of specifications.
