If memory serves correct...I go through the wheel well, and here's a little trick (saves you from cross threading) get a short piece of fuel line..3-4 inches, stick it on the new plug and use it to thread in the new plug finger tight before putting a wrench on it. Hope you're using anti sieze on the new plugs?

Did you have to remove anything to get to it (hoses, etc)?
Are you saying you could get a socket on it but not loosen it or that you couldn't get a socket on it?
I changed mine on my 86 and don't remember anything especially different, could be that there is something in the way on a 91.
I changed the spark plugs on my '90 and it really wasn't a big deal. Not like a Mitsu 3000GT VR4, you might as well buy a new car when it comes time to change the spark plugs.
First I would spray it with some liquid wrench or something, and then let it sit for a couple of hours if possible. Then try to take it out. Make sure not to use an extension if you do not have to, or anything else. Just the socket and the ratchet or breaker bar.
For reinstalling, I like using either a piece of fuel line as already sugested or my spark plug installation too, (Better know as an old spark plug boot off the old wires before I threw them away the last time). I used to have one of those fancy real spark plug installation tools, but found the boot off of an old set of Autolite plug wires worked better.
To access the plugs on the passenger side I remove:
-the wheel well access panel
-two AIR hoses
-A/C compressor rear brace
For plugs #2 & #4 I go in through the wheel well opening with a 3/8" socket, extensions & swivel. Of course I hand start the new plugs before going to the socket.
Put a plug socket on the plug and then use an openend wrench to remove the plug using the nut on the end of the socket. Install the same way. Plugs only need to be snug and don't forget anti seize compound.
