Cars been running fine the past three months since I gotten back and started driving it again. Drove the car in the rain the night before. Comes morning time the car was shaking. Didn't drive well and sputtered the whole time on low RPM. Just wanted to see some help on this. Probably someone had the same problem before. My car is Automagic, 91. Maybe rain has nothing to do with it or just because I started driving her more. By the way my car engine coil covers are not present on the car. Both front and back are missing. Gonna need to get these parts too.:frown:
Car shaking on idle like its missing.

Pull your coils, check your plugs (I'd just put new ones in there since you've gone through that much effort..). Most likely you have moisture in there. 99.9% that is your problem.
what happens when you quickly whip the gas pedal raising to about 2k rpm then quickly letting off. I may be able to help if rpm is fuctuates from 0-700.
You didn't mention getting a CEL but a bad O2 sensor can create the same symptoms you're experiencing and not throw a code. If that turns out to be the problem, get new ones at sparkplugs.com.
I replaced all spark plugs this evening and I drove the car for 20 minutes after that. Everything seem normal now. What I've noticed when I was changing the plugs was that one of the spark plugs had a little liquid on it. The very back drivers side corner that is. My engine is missing the ignition coil covers. This might have caused the rain I encountered last week to finally damage that one area. I called the dealer for the covers today and they run about $91 each for front and back. Hopefully nothing will happen to my car now since I done this. Now I'm going to search for the covers here if anyone has a better price. If not then I'll just get the OEM from the dealer. Thank you for all of your feedbacks.
It sounds like you may have a bad seal on one of your coil packs. Probably on the rear bank? When you say that there was liquid on one of your spark plugs was it on the combustion chamber side or on the coil end? The coil has a seal on it that seals to the valve cover and the long plastic cover that goes over the three coils has a seal along the top edge of it. You may want to check those.
