Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts during the repair.
Ensure the vehicle is on a level surface and use wheel chocks for safety.

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter and clean the housing with a damp cloth.
Install the new air filter, ensuring it is seated properly.
Reassemble the housing and secure it with screws or clips.

3. Fuel Pump Inspection

Access the fuel pump (may require removing the fuel tank or accessing through the rear seat).
Disconnect the fuel lines and electrical connector.
Remove the fuel pump assembly from the tank.
Inspect the fuel filter for clogs and replace if necessary.
Install the new fuel pump and reconnect the fuel lines and electrical connector.

4. Throttle Position Sensor (TPS) Replacement

Locate the TPS on the throttle body.
Disconnect the electrical connector from the TPS.
Remove the screws securing the TPS to the throttle body.
Install the new TPS, aligning it properly.
Reconnect the electrical connector and ensure it clicks into place.

5. Transmission Fluid Change

Raise the vehicle and support it securely on jack stands.
Drain the old transmission fluid by removing the drain plug or pan.
Replace the transmission filter if applicable.
Reinstall the drain plug and refill with the correct type of transmission fluid using a funnel.
Start the engine and allow it to reach operating temperature while checking for leaks.
