why are you removing inj. to repl spark plugs?

You dont need to remove the fuel rail or the injectors. Just remove the 7mm bolt on the coil. The coil has a rubber boot on it that will bend to allow you to remove it. Make sure you check inside the spark plug tube before you remove the plug. You need to check for water or oil in there. If not dry, you have a leak that needs to be fixed.
