Which spark plug do you take off first?
The first step in changing your spark plugs is to remove the old ones. To avoid turning this job into an all-weekend project, remove one spark plug at a time, inspect it, clean it, and — if it’s salvageable — gap the spark plugs. Then replace it before you move on to the next spark plug in cylinder sequence order.
Do you have to disconnect battery before changing spark plugs?
