On my 99 you remove the black plastic covers, then pull each plug wire/coil boot off, then use a long extension to reach down in and loosen/unscrew each plug. If you don't have a grip socket, use a piece of rubber fuel line/hose to reinstall the new plugs...ie. stick the end of the plug into the end of the hose, lower hose into head, turn hose to get plug started, remove hose and then tighten with your socket and extension. Should be about the same on your 01.
