If you look at the plugs, you will see wires that go to three "black boxes" bolted to the side of the engine. These are the coils. You can buy a coil tester from KMS tools or similar stores that sell automotive tools. It comes with instructions. Sometimes a coil can be intermittent, though. If you know some one with a 3.8, you could try swapping coils and see if that fixes your problem.
Wires are cheap, so I'd replace them anyway. I usually stay with GM wires, they seem pretty good. Just make sure they follow the same routing as the old ones you remove. I usually do one at a time so I guarrantee the go on the way the came off.
There are other causes for your symptoms, but I consider plugs AND wires to be part of a regular maintainance thing. If you get your hands on a good scantool, you can determine what plug is misfiring. Then you can move coils around and see if the missfire moves to a new cylinder. If so, then it's your coil.

enslow, you're correct. The 95 Regal, 3800 V6 doesn't have a distributor. I'll check the coils next to see if they are the problem after I take a look at the PCV valve.
Right now, I'm trying to check the PCV valve. However, my manual is leading me to the wrong spot. It was telling me the PCV valve was under the MAP sensor. But I think the PCV valve is to the left of the engine, and to the right of the alternator. There's a cylindrical thing attached to the engine with "PCV" written in two places on top. That seems to be a pretty obvious indicator that it's the PCV valve.
So assuming that's the PCV valve, but unfortunately I'm still stuck. I'm trying to get the PCV valve off, and I can't figure out how to do it. I'm guessing I have to push down and turn it counter-clockwise, but I can't get any force on it. Is there a special tool you need to remove the PCV valve? What makes it tough is I have some wiring running right on top of the PCV valve, and I have to use one hand to hold the wiring out of the way, which only leaves me one hand to try to rotate the PCV valve.
