Where are the spark plugs located on a 1997 Cadillac Catera?

there is two bolts on the intake manifold to the bundle of wires on the drivers side take them out and there is a plug in front of the wires and one on the side unplug them move the wires to the side and you should be able to get to the spark plugs a lot easier than taking the manifold off. on mine had to change valve cover gaskets its a little bit of a job.
