Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.

2. Addressing Air Intake Issues

Remove the air intake duct.
Inspect and replace the engine air filter if clogged.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reassemble the air intake duct securely.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "On" position (do not start the engine) and check the pressure reading.
If pressure is below specifications, check the fuel pump, fuel filter, and fuel lines for clogs or leaks.
Replace any faulty components and ensure proper connections.

4. Ignition System Check

Remove spark plugs and inspect for wear or fouling.
Replace worn or damaged spark plugs with the manufacturer's recommended type.
Test ignition coils with a multimeter to ensure proper resistance; replace any faulty coils.

5. Exhaust System Examination

Inspect the exhaust system for visible signs of damage or blockages.
Check the catalytic converter for clogs by performing a backpressure test if necessary.
Replace any damaged exhaust components, including the catalytic converter if needed.
