Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuel Filter

Locate the fuel filter, usually situated along the fuel line.
Relieve fuel system pressure by disconnecting the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using a line removal tool.
Remove the fuel filter using a wrench and replace it with a new one.
Reconnect the fuel lines securely and replace the fuel pump fuse.

3. Clean or Replace Air Filter

Open the air filter housing, typically held by clips or screws.
Remove the air filter and inspect for dirt and debris.
Clean the filter with compressed air or replace it with a new one if it’s too dirty.
Reassemble the air filter housing and ensure it is sealed properly.

4. Test and Replace Throttle Position Sensor (if necessary)

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the sensor.
Use a multimeter to test voltage readings against specifications (consult the repair manual).
If readings are out of spec, replace the TPS with a new one and reconnect it.

5. Inspect and Replace Spark Plugs

Remove the ignition coils or spark plug wires to access the spark plugs.
Use a spark plug socket and ratchet to remove the old spark plugs.
Inspect for wear and replace with new plugs, ensuring correct gap size.
Reinstall the ignition coils or spark plug wires.
