Solution

1. Preparation

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

2. Replace Air Filter

Remove the air intake duct to access the air filter.
Replace the old air filter with a new one.
Reassemble the intake duct securely.

3. Fuel System Check

Connect the fuel pressure gauge to the fuel rail.
Start the engine and check the fuel pressure against manufacturer specifications.
If pressure is low, replace the fuel pump. If pressure is acceptable, proceed to inspect fuel injectors.

4. Inspect and Replace Ignition Components

Remove the ignition coils and inspect spark plugs for wear (look for signs of fouling or damage).
Replace worn spark plugs with OEM specifications.
If ignition coils appear damaged or weak, replace them.

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold.
Clean the throttle plate and inside of the throttle body with throttle body cleaner.
Reinstall the throttle body and reconnect all associated electrical connectors.

6. Vacuum Leak Repair

Inspect all vacuum lines for cracks or disconnections.
Replace any damaged hoses and ensure all connections are tight.
