Look in the required maintenance booklet that came with the vehicle. Probably 90 or 100 thousand miles.
how do I change spark plugs on 2002 Toyota tacoma v4
Change the plugs and wires at 100,000 miles unless you experience poor performance or a drop in MPG. In that case change them sooner.
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.
Change the plugs at 100,000 miles or earlier if the engine is not performing as it should.
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.
Sorry, but you are badly mistaken. There are six spark plugs on the V6 Toyota Tacoma.
