Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Air Filter

Sub-steps:
- Open the hood and locate the air filter housing.
- Remove the screws or clips securing the air filter cover.
- Take out the old air filter and inspect for dirt or damage.
- Install a new air filter (use OEM or high-quality aftermarket).
- Reassemble the air filter housing and secure it properly.

3. Test and Adjust Fuel Pressure

Sub-steps:
- Locate the fuel rail and attach the fuel pressure gauge.
- Start the engine and observe the fuel pressure readings.
- If pressure is below specifications (consult service manual), replace the fuel pump.
- If the fuel pump is fine, check for clogged fuel injectors and clean or replace as necessary.

4. Clean Throttle Body

Sub-steps:
- Remove the air intake duct connected to the throttle body.
- Use throttle body cleaner and a soft cloth to gently clean the interior surfaces.
- Ensure the throttle plate moves freely and is properly lubricated.
- Reattach the air intake duct securely.

5. Check and Replace Spark Plugs

Sub-steps:
- Remove the ignition coils or wires to access the spark plugs.
- Inspect the spark plugs for wear or fouling.
- Replace with OEM spark plugs, ensuring proper gap specifications.
- Reinstall ignition coils or wires.
