2002 Cadillac DeVille Question: miss at idle and it hesitates when I start up



Visitor, Columbia, MO, March 12, 2010, 15:16

I have a miss at idle and it hesitates when I start up. Seems like it needs a tune up. How do you change the plugs and wires on a 2002 Cadillac Deville?

    your car has a coil on plug igniton which means there are no wires to replace. I would try replacing the spark plugs with new platinum plugs. If this doesnt help u may need new coil assembly.

    to access the plugs u need to remove the service cover and black radiator cover that is right in front. Next you need to disconnect the electrical plugs from the 4 front coil/boot assemblies. unscrew the 4 assemblies using an alan wrench. The coils should pull straight up and out. underneath them is the plugs. They are seated pretty deep so have a few extensions ready. good luck!
