You can change the spark plugs on the 1997 Toyota Tacoma yourself. Remove the ground wire and spark plug wire. Remove plug. Replace the plug with a plug made specially for your model car.
When changing the spark plugs on a 2006 Toyota Tacoma make sure the vehicle is off. Use a spark plug socket and pull the spark plug wires. Remove the old spark plugs and properly space and install the new parts.
The 2006 Toyota Tacoma V-6 engine spark plugs can be removed with a 5/8 deep well socket. Turn the socket to the left to remove the spark plugs.
they are attached to the ends of the spark plug wires
