Solution

1. Preparation

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

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits securely, and reattach the housing cover.

3. Inspect and Replace Spark Plugs

Remove the ignition coil using a socket set and disconnect the electrical connector.
Unscrew the spark plug using a spark plug socket and inspect for wear.
Install new spark plugs, torquing to manufacturer specifications (typically 13-15 lb-ft).
Reinstall the ignition coil and reconnect the electrical connector.

4. Fuel System Check

Use a fuel pressure gauge to check the fuel pump pressure against manufacturer specifications.
If below spec, replace the fuel pump as necessary, following these steps:
- Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
- Disconnect the battery and remove the fuel tank as per the service manual.
- Replace the fuel pump and reassemble the tank, ensuring all connections are secure.

5. Throttle Position Sensor Testing

Disconnect the TPS electrical connector.
Use a multimeter to check resistance across the terminals while moving the throttle plate.
If readings are inconsistent, replace the TPS following these steps:
- Remove the mounting screws using a socket set.
- Install the new TPS and reconnect the electrical connector.
