Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to avoid electrical issues during repairs.

2. Inspect and Replace Air Filter

Remove the air filter housing cover.
Take out the old air filter and inspect for dirt and clogs.
Install a new air filter (ensure it matches OEM specifications).
Reattach the air filter housing cover securely.

3. Fuel System Inspection

Remove the fuel pump relay to disable the fuel pump.
Attach the fuel pressure gauge to the Schrader valve on the fuel rail.
Turn the ignition to the "On" position (do not start the engine) and check the pressure reading.
If pressure is below specifications (typically 50-60 psi), replace the fuel pump.
Reinstall the fuel pump relay and ensure all connections are secure.

4. Spark Plug and Ignition Coil Check

Remove the engine cover (if applicable) to access the ignition coils.
Disconnect the electrical connector from each ignition coil.
Use a socket wrench to remove the ignition coils from the spark plugs.
Inspect spark plugs for wear; replace if necessary (gaps should be set to manufacturer specifications).
Reinstall ignition coils and connectors.

5. Vacuum Leak Repair

Visually inspect all vacuum lines for cracks or disconnections.
Replace any damaged vacuum lines with OEM parts.
Reconnect all vacuum lines securely.
