Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery negative terminal to ensure safety.

2. Address Faulty Components

A. Replace Spark Plugs

Remove the ignition coils using a socket set.
Unscrew the old spark plugs with a spark plug socket.
Install new spark plugs, ensuring they are torqued to the manufacturer’s specifications (typically 20-25 Nm).
Reattach the ignition coils.

B. Clean or Replace Air Filter

Open the air filter housing by loosening the clips or screws.
Remove the old air filter and inspect for dirt and debris.
Install a new air filter (ensure it fits snugly) and secure the housing.

C. Clean Throttle Body

Remove the air intake duct attached to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
Reassemble the air intake duct securely.

3. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (without starting) to check fuel pressure; it should match manufacturer specifications (typically around 50-60 psi).
If pressure is low, consider replacing the fuel pump or fuel filter as necessary.
