Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Air Intake

Remove the air intake duct and inspect for blockages or debris.
Clean the air filter or replace it if dirty.
Reinstall all components securely.

3. Fuel System Check

Connect the fuel pressure gauge to the fuel rail.
Start the engine and monitor the fuel pressure against specifications (usually around 50-60 psi for most gasoline engines).
If pressure is low, check the fuel pump and replace if necessary.

4. Ignition System Inspection

Remove the ignition coils and inspect them for cracks or damage.
Replace any faulty coils and spark plugs as needed.
Reinstall ignition components securely.

5. Throttle Body Service

Remove the throttle body from the intake manifold.
Clean the throttle plate and bore using throttle body cleaner.
Reinstall the throttle body and reconnect any sensors.

6. Exhaust Inspection

Inspect the exhaust system for any visible damage or blockages.
If the catalytic converter appears clogged, it may need to be replaced.
Ensure all exhaust connections are tight and leak-free.
