how do you change the back 3 spark plugs and wires on a 1998 lesabre limited it does not ave dogbone struts
probally have to loosen up the motor mounts, and the tranny mounts, support the engine and try to get enough room to move it forward to access the rear plugs
the method jacob suggests is actually given in the early 1980's service manual of GM. i did it blindly from the bottom of the car but i had trouble with #6 on the 2000 model. my slim hands made it do-able but it still can be bruising using different extentions without loosening the motormounts. on the wires, remove the oil neck then remove shroud and trace wiring. #6 plug was unsuccessful for me. good luck.
i have a 2001 buick le sabre . it runs rough at idle and stop signs
