How do you do a spark plug tune up on 2006 model Toyota corolla?

Answer 1

You'll need is a 5/8" Spark Plug Socket with a 6" extension and a wrench to be able to get in all the way. The spark plug socket has a rubber cone inside so it grips onto the plug and makes it easier to pull out. You will also need a 10mm socket to take off the engine cover, and each individual ignition coil.

1st remove the engine cover by removing the 2 bolts and the 2 clips

Once that is done, you will see an exposed valve cover and 4 coil packs. undo each coil (using a size 10mm socket and wrench) pack and pull up on them to get it off the spark plug hole. Do these one at a time (recommended). Put in your spark plug socket with the extension and start unscrewing. After removal, put in the new plug and tighten till it wont go any further. NO RECOMENDED TORQUING SETTING.

Just tightened them to a little past where your hand would need some effort from the other hand. repeat for other spark plugs.
