Solution

1. Preparation

Gather tools and parts required.
Disconnect the battery to ensure safety while working on electrical components.
Ensure the vehicle is on a level surface and properly supported.

2. Replace Air Filter

Locate the air filter housing.
Remove the clips or screws securing the housing.
Take out the old air filter and clean the housing area.
Install the new air filter, ensuring it fits securely.
Reassemble the air filter housing.

3. Check and Replace Fuel Filter

Locate the fuel filter (usually along the fuel line).
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.
Remove the old fuel filter and install the new one, ensuring correct direction of flow.
Reconnect the fuel lines and reinstall the fuel pump fuse.

4. Inspect and Replace Ignition Components

Remove the ignition coils by unscrewing them from the engine.
Take out the spark plugs using a spark plug socket.
Inspect the spark plugs for wear and replace if necessary.
Reinstall new spark plugs with proper torque (typically 15 ft-lbs).
Reinstall ignition coils, ensuring they are secure.

5. Test and Adjust Throttle Position Sensor

Locate the TPS on the throttle body.
Disconnect the TPS connector and measure the voltage using a multimeter.
If the voltage is outside of specifications, replace the TPS.
Reconnect the TPS and check for proper function.
