Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and turn off the engine.
Disconnect the battery (negative terminal) to prevent electrical shorts.

2. Inspect and Clean Air Intake System

Tools Required: Flathead screwdriver, cleaning solution (MAF cleaner)
Remove the air intake duct and inspect the mass air flow (MAF) sensor.
Clean the MAF sensor using the appropriate cleaning solution and reattach the duct.

3. Test Fuel System Pressure

Tools Required: Fuel pressure gauge
Locate the fuel rail on the engine and connect the fuel pressure gauge.
Turn the ignition to the "ON" position (without starting the engine) and check the pressure; it should match the manufacturer's specification.
If pressure is low, inspect the fuel pump and filter for issues.

4. Clean or Replace Throttle Body

Tools Required: Socket set, throttle body cleaner
Remove the throttle body from the intake manifold by unscrewing it.
Clean the throttle body with throttle body cleaner and a soft brush.
Reinstall the throttle body and reconnect any electrical connectors.

5. Inspect Ignition System

Tools Required: Socket set, spark plug wrench
Remove the spark plugs and inspect for wear or carbon buildup.
Replace any faulty spark plugs and check the ignition coils for proper operation.

6. Check Exhaust System

Tools Required: Jack and jack stands, wrench set
Lift the vehicle and inspect the exhaust system, focusing on the catalytic converter and muffler for any blockages or damage.
If the catalytic converter is clogged, it may need to be replaced.
