CAN I CHANGE MY OWN SPARK PLUG WIRING ON A P7 GRAND AM RATHER SIMPLY?sPARK PLUG WERE CHANGED ALREADY ABOUT A MONTH AGE AND I DIDN'T GET THE WIRES CHANGED.

If the coil packs are factory they will have the firing order marked on them and the intake should have your cylender number on it start with 1 pull the wire off the plug take the wire out of the plug wire harness take off the coil and replace. Do the following to the next five you might have to take off some of the plastics to get to them. If you have not did this very much it can be nerve racking use some diode grease when putting back together it keeps the contacts free of corosion and makes it easier to pull off for replacement in the future.thanks

Yes you can, just make sure you put the wiring in the correct order, the best way to do this is change one wire at a time.
