Solution

1. Preparation

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

2. Air Filter Replacement

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter that meets OEM specifications.
Reattach the housing cover securely.

3. Fuel System Inspection

Locate the fuel rail and connect the fuel pressure gauge.
Turn the ignition to the "ON" position (without starting the engine) to check fuel pressure; it should meet manufacturer specifications (usually around 50-60 psi).
If pressure is low, inspect and replace the fuel pump or fuel filter as necessary.

4. Throttle Body Cleaning

Remove the intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reinstall the intake duct securely.

5. Spark Plug Replacement

Remove the ignition coils or spark plug wires carefully.
Use a socket wrench to remove the spark plugs and inspect them for wear or deposits.
Install new spark plugs, ensuring they are gapped to manufacturer specifications.
Reattach the ignition coils or spark plug wires.
