Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off and cool.
Disconnect the battery before beginning work on electrical systems.

2. Addressing Check Engine Codes

Connect the OBD-II scanner and retrieve any stored codes.
Research the codes and determine the necessary repairs.
Clear the codes and test drive the vehicle to see if they reappear.

3. Inspecting the Air Intake System

Remove the air filter and inspect for dirt or damage. Replace if necessary.
Check the intake hose for cracks or loose connections and replace as needed.

4. Testing Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check the pressure.
Compare the reading to manufacturer specifications (typically around 50-60 psi for most models). Replace the fuel pump if pressure is low.

5. Examining the Ignition System

Remove spark plugs and inspect for wear or fouling. Replace plugs if necessary.
Test ignition coils with a multimeter for proper resistance. Replace any faulty coils.

6. Testing the Throttle Position Sensor

Disconnect the sensor and test its output voltage with a multimeter.
Compare readings to specifications. Replace the sensor if it is out of range.

7. Inspecting the Exhaust System

Check for any visible damage or leaks in the exhaust system.
Use a smoke test to identify internal obstructions such as a clogged catalytic converter. Replace as necessary.
