Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.
Allow the engine to cool if it has been running.

2. Air Intake Inspection

Remove the air intake duct using a socket set.
Inspect the air filter for dirt or clogging; replace if necessary.
Check for any cracks or loose connections in the intake hoses.

3. Fuel System Check

Locate the fuel pressure test port on the fuel rail.
Use a fuel pressure gauge to check the fuel pressure; it should be within manufacturer specifications (usually 30-50 psi).
If pressure is low, inspect the fuel pump, fuel filter, and fuel injectors for issues.

4. Ignition System Inspection

Remove the ignition coils from the spark plugs.
Check the spark plugs for wear or fouling; replace if the electrodes or insulator are damaged.
Test the ignition coils for proper resistance with a multimeter; replace any faulty coils.

5. Exhaust System Examination

Visually inspect the exhaust system for any visible damage or blockages.
Check for any rattling sounds that may indicate a failing catalytic converter.
If necessary, remove the exhaust pipe to inspect the catalytic converter.

6. Throttle Position Sensor Verification

Locate the throttle position sensor on the throttle body.
Use a multimeter to measure the voltage output while manually moving the throttle plate; ensure it varies smoothly and within specification.
Replace the throttle position sensor if it does not meet specifications.
