Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool if necessary.

2. Inspect and Replace the Air Filter

Remove the air intake duct using a socket set.
Take out the air filter and inspect it for dirt or blockages.
Replace with a new air filter if necessary, ensuring it is seated correctly.
Reattach the air intake duct securely.

3. Check and Adjust Fuel Pressure

Locate the fuel pressure test port on the fuel rail.
Connect a fuel pressure gauge to the test port.
Start the engine and check the fuel pressure reading against manufacturer specifications.
If pressure is low, replace the fuel pump or fuel filter as needed.

4. Clean the Throttle Body

Remove the throttle body from the intake manifold using a socket set.
Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
Reinstall the throttle body and ensure all connections are secure.

5. Inspect Ignition System

Remove the spark plugs using a spark plug socket.
Check for wear or damage on the spark plugs and replace them if necessary.
Test ignition coils with a multimeter for proper resistance values.
Replace faulty ignition coils as needed.
