Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and visually inspect it for dirt or damage.
Replace the air filter with a new one if it's dirty or damaged.
Reassemble the air filter housing securely.

3. Fuel Pressure Check

Connect the fuel pressure gauge to the fuel rail test port.
Turn the ignition key to the "On" position without starting the engine to check the fuel pressure reading.
If the pressure is below the manufacturer's specification, replace the fuel pump or filter as needed.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold using a socket set.
Use throttle body cleaner and a soft cloth to clean the interior, especially around the throttle plate.
Reinstall the throttle body and ensure all bolts are torqued to the manufacturer’s specifications.

5. Spark Plug Inspection and Replacement

Remove spark plug wires or ignition coils carefully.
Use a spark plug socket to remove spark plugs and inspect them for wear or fouling.
Replace any worn or fouled spark plugs with manufacturer-recommended parts.
Reinstall spark plug wires or ignition coils.

6. Check for Vacuum Leaks

Visually inspect all vacuum lines and gaskets for cracks or disconnections.
Replace any damaged hoses or gaskets to eliminate vacuum leaks.
