Update. The miss is gone, I cleared the code and it hasn’t come back. To be honest I didn’t expect for it to come back because the car isn’t missing but I was worried about something else showing up as a result of a greater problem. I cannot explain the bang I heard twice when backing up yesterday. And now the oil pressure gauge is acting properly as well. At idle it is at about 40 and it fluctuates while the motor is put under load. But now I have another problem which is just absolutely crazy. I lost control of my vents. The air is only coming out at the window no matter what I change it to. Auto, AC, Off/On, start the car, it doesn’t matter.
Conclusion, the coil went bad and blew the ICM. When I brough the ICM and coils into Auto Zone they put the multimeter on it (right in front of me) and it tested out. So I replaced the plugs (AC Delco Irridiums), wires, and ICM and had the same problem. Swapped the wires on the 3/6 coil and the misfire moved. Replaced the coil and now I am fixed.
But why did I lose control of my vents? Could have I bumped something back on the firewall when I was installing the plugs to the 2/4/6 cylinders?
Again I want to thank everyone especially Dan and Bill. I really thought she was a goner.

On the firewall, there should be a little bump about in the middle. That'* your blower motor. Make sure that the little L-shaped vacuum tube running from there is intact. If it'* not, you won't get anything but the defroster.

It is possible your ground bus connections are corroded. There'* a write up by Toddster in tech info about that, electrical I think. That could cause your dash problems. Check them out and clean them up.

Well if you are talking about the elbow it is intact. I actually had problem with my blower and took it out a month ago and blew it out with a air because it was working intermittently. But I am missing a hose that goes on right near the BCA. I can post a pic but i think I can explain it good enough. Okay the BCA has a hose coming out of it going towards the front of the car. Where that hose plugs into there is a place for an additional hose right above it. I do not have that hose. I think I remember it being a vacuum line that broke but i cannot remember. Can someone tell me where th ehose goes and what it does. I will replace it today.
Thanks
Thanks

Dan do you see the green highlighted box in your picture? There is a little nozzle in the middle of it. You don't have a hose going to it as well so I don't know what that means.

So much for a simple solution to my vent control issue. Can you point me to the direct of a vacuum line diagram that might help? What service manual do you recommend?
