undo motor mount in front and put jack under engine and gently lower engine until you can see back plugs
Well, if you want to make it harder on yourself, you can change them the way I did on my 98 Grand Prix. Don't mess with motor mounts and just try to reach back there using a mirror and skinny hands to pull wire off, untighten, replace, retighten, wire back on, and lose 2-3 tools in the engine compartment that never fell through to the ground. It was fun!!
Make sure the car wheels are chocked. Be on level ground. Make sure the transmission is in Park. Remove the forward most bolts in each of the two motor mounts in front of the engine. Have someone help you push the car forward and the engine will move away from the firewall as you do this. once you get the car forwrd enough make sure you have the wheels chocked again so the car can't roll backwards. You will see an "eye" on the bottom of the motor mount that you can stick the bolt back trough once you get the engine rocked forward enough. Once you get the bolt in the eye you will have plenty of room to get down behind the engine. You can go further if you don't want to use the bolt through the eye. Just push the car forwrd even more and chock the wheels again. You will want to make sure that whatever you have securing the wheels will not come out. You wouldn't want it to happen and get you arm pinned in between the firewall and the engine.
Just changed spark plugs on my 98 Grand Prix with 3.8L V-6. Was able to get to back spark plugs without moving engine, although you may skin some knuckles--my hands and arms are not skinny. The hardest part was removing the old wires--twist the boot first to break them free from the spark plug before trying to remove them. I also replaced the wires as a precaution and since I found some cracks at the wire-to-boot base. You will need a ratchet with a flex head and a short extension between the ratchet and spark plug socket to ease removal. Using dielectric grease on the boot before installing it on the new plugs should ease removal of the wire in the future if you need to.
On my '91 Cutlass, with the 3.1L, the easiest way I found to change the back three spark plugs was to remove the serpentine belt and then remove the alternator. Then had all the space I needed to change the plugs.
Switch off the car and then pull out the spark plug wires by holding them from the plug boot. Remove the spark plugs using a socket wrench and clean off any dirt or debris that is left in the spark plug hole. Replace the plug and tighten them first by hand and then by wrench. Reattach the wires.
Its not easy, the motor basically needs to be tilted forward and is a process most people should not do. This is why many "tune ups" are now so costly. And by the way, dont cheap out...buy the best plugs you can get when changing as you DONT want to do this again for a very long time!
The plugs on the front of the engine are pretty straight forward to change. I change the rear plugs by removing the coil tower and unhooking both plug in wire groups. however I leave the spark plug wires hooked up to the tower after marking them and removing them from the plugs. I lay a cardboard mat on the engine and lay on it. Those back plugs are now exposed and reletivly easy to get to. People with big hands like me can get to them easily.
Disconnect the car battery, disconnect the spark plug cables, and remove the old spark plugs. Next put in the new spark plugs, re-connect the spark plug cables and connect the car battery.
The plugs are under the coil. Just remove the coil and there they are.

You must loosen the top motor mount and tilt the engine forward.
