Question about 1997 Buick LeSabre
These are pretty hard to do even for an experienced tech. The only way to do it with any time consuming mearsure is to feel your way around. You will end up using a 3" and 1" extension, long handle 3/8" ratchet that will allow you to break them loose, and then a short handle to screw them out. Take off one wire at a time and replace the spark plug. Use anti sieze on the threads of the plugs and be sure to use AC Delco plugs or you will get either driveability issues or a check engine light on for what will seem like no reason. It would also be a good idea to use di electric grease on the end of the wire before you install it. Let me know if you need anything else.
