How do you change the toyota echo spark plugs?
The spark plugs are underneath that cover on top of the engine (on mine the cover says VVTi). Just take that cover off, and then you will see the four ignition coils. Take off the four ignition coils (with igniters), and you will see the four relatively long holes underneath, and the spark plugs are at the bottom of those holes. You will need a good spark plug socket (preferably a thin wall socket) and a 6″ or 12″ extension. This is actually a very easy job, and can be completed in less than an hour.
