Loose Spark Plug
Had my 93 for about a month now. It had sat without running since Sept of last year. Since I have owned it I have put about 300 mile on it and had a constant rough idle. Felt like a bad wire or plug. Pulled an easy plug and seen it had Bosch plugs. I never have felt real comfy with Bosch so I went out and got some NGK plugs today and figured on an afternoon of fun and festivities. Not sure it was good timing since I smashed a knuckle on my left hand last week. Any how about 4 hours later and a few beers 
I did right side first as it appeared the easiest (WRONG) Finally got to the left side and the very front plug was never tighten. Was about 4 full turns loose. Installed all the NGK's and went for a run. Very smooth, feels like new. And here I was thinken new Opti, pressure reg etc etc. 
happy as a gal buying new shoes now. $17 fix can't beat that. Just a little more info for the memory banks if ya have a rough idle.

Glad it worked out for you 
you might want to check it a few times to make sure it was just lose and not a stripped plug hole-these
are aluminum heads-here's a little secret-next time get a short length
of rubber gas hose, one that slips snuggly onto the plug (I use about 4-5 inches) and use it to get your plugs started and as snug as you can before putting a plug wrench to it-makes life easier and you won't need to worry about cross threading the plug hole.

Rick,,,don't say stripped plug hole. If I ever install a helicoil again it will be too soon. haha Thanks for the hose tip though, appreciate it. I like to use a cut off end from an old silicone calk tube and tap it into my deep well socket. Starting the plug with the socket and antiseize compound it gives more feel in tight places and once snug the tube end will slip loose. socket is already in place for torque wrench then. Ya might like to try that also.
