Many cars are programmed so that the RPMs in park/neutral are limited. My wife's S80 behaves that way -- can't bring it above 4500RPM in P or N. You need to check it out on the road, not when parked.
If it's a 5.4, the plugs are loated under the coilpacks. You need to remove one of the 8 coilpacks, then you will see the sparkplug down a deep hole.
on the 3.5 v6 take off the engine cover, unscrew the coilpacks and take out the spark plugs.

1998 Volvo V70 GLT ~ After tune up I'm getting a check engine light that says misfire in all 5 cylinders. Used NGK copper plugs. The car runs like a champ but wont pass emissions. What do I do?
If bad plugs is causing the misfire. It could also be bad plug wires, a vacuum leak, burnt valve, blown head gasket, etc.

The Concorde could misfire for several reasons. Start by checking for proper fire to the spark plugs. Then check engine compression to see if a cylinder compression is down.
