Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Replace Air Filter

Remove the air filter cover by loosening the retaining clips or screws.
Take out the old air filter and inspect it for dirt and damage.
Install a new air filter, ensuring it is seated properly.
Reattach the air filter cover securely.

3. Fuel System Inspection

Locate and access the fuel pump (may require removing the rear seat or accessing the fuel tank).
Use a fuel pressure gauge to check the fuel pressure against manufacturer specifications.
If pressure is low, replace the fuel pump as needed.
Clean or replace fuel injectors if they are clogged. Use a fuel injector cleaner if necessary.

4. Throttle Position Sensor (TPS) Replacement

Disconnect the electrical connector from the TPS.
Remove the TPS from the throttle body using a suitable socket.
Install the new TPS and reconnect the electrical connector.
Ensure the TPS is calibrated according to service manual specifications.

5. Check for Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to identify leaks.
Replace any damaged hoses and ensure all connections are secure.
