how do you change the back 3 spark plugs and wires on a 1998 lesabre limited it does not ave dogbone struts
3.1 v6? first u have to b determined to get it done. also use different lengths of extensions. its best if u have small arms but u have to just reach back there and do it. to install plugs, obtain a 6in length of vacuum line( 6in is just approx., do what u want). insert the tip of the spark plug into the line(not the threaded end). place the plug in the spark plug hole and twist the vacuum line to get the threads started. then tighten down with what ever variation of extensions and determination u used to remove them.
