Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Safety glasses and gloves should be worn.

2. Inspect and Replace Fuel Filter

Locate the fuel filter (refer to the vehicle manual for specific location).
Use a socket set to remove the fuel filter from its housing.
Install the new fuel filter in the same orientation as the old one.
Reconnect fuel lines and ensure they are secure.

3. Test and Replace Fuel Pump (if necessary)

Reconnect the battery and turn the ignition to the "ON" position without starting the engine to prime the fuel system.
Use a fuel pressure gauge to check the fuel pressure; it should match manufacturer specifications.
If pressure is low, remove the fuel pump from the tank (refer to the service manual for detailed instructions).
Replace the fuel pump with a new unit, ensuring to reconnect all electrical connectors and fuel lines securely.

4. Clean or Replace Air Filter

Open the hood and locate the air intake box.
Remove the air intake cover using a screwdriver or socket set.
Take out the air filter and inspect it for dirt or damage.
Replace it with a clean air filter if necessary, ensuring proper seating.

5. Inspect and Replace Throttle Position Sensor (if faulty)

Disconnect the electrical connector from the throttle position sensor.
Remove the sensor using a socket set.
Install the new throttle position sensor and reconnect the electrical connector.
Ensure the TPS is calibrated, if necessary, per manufacturer specifications.
