Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative terminal of the battery to prevent electrical shocks.

2. Clean or Replace Air Filter

If the air filter is dirty:
- Remove the air filter housing cover using a socket set.
- Take out the old air filter.
- Install a new air filter, ensuring it fits snugly.
- Reattach the air filter housing cover and secure it.

3. Inspect and Clean Throttle Body

Locate the throttle body:
- Remove the intake duct connected to the throttle body.
- Use a throttle body cleaner and a soft cloth to clean the interior of the throttle body.
- Ensure the throttle plate moves freely.
Reconnect the intake duct securely.

4. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter:
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect the fuel lines from the filter using a line removal tool.
- Replace the old filter with a new one and reconnect the fuel lines, ensuring there are no leaks.

5. Test Fuel Pressure

Reconnect the fuel pump fuse and turn the ignition to the "ON" position without starting the engine.
Use a fuel pressure gauge to check if the pressure meets manufacturer specifications (typically 40-50 psi).
Replace the fuel pump if the pressure is inadequate.
