trying to find out how to change spark plugs [from top or bottom.
from the top. they are by the fuel rail under the coils. very labor intensive job. it takes close to 3 hours in a shop with all the stuff you have to remove and get out of the way to access the plugs.
if you have never done this operation, i recommend letting a shop do this for you.
