hi there, if you havent changed a distributor before then i would get a mechanic to check it.. the way it works is very confusing and if it is the slightest bit out it will not run or it will run rough...
if you have it right then you should be able to adjust it by loosening the bolts and rotating the cap but be very carefull as you are dealing with potentialy fatal amounts of current when the engine is benig turned over .

If this excessive swaying is due to worn suspension then those worn parts will be tie-rods, shock struts, anti roll bars and the rubber bushings holding the various parts of the suspension in place. General suspension overhaul would be required.
Now if its a normal feature of the vehicle you can improve the handling by fitting harder anti roll bars(sway bars), stiffer shocks, custom tie rods, better quality rubber bushes (polyurethane) and by lowering the suspension with shorter stiffer springs.
I suggest searching for an owners club for your vehicle where you should find some people who are doing the same thing and get advice from those who have been there before - --- You can ruin a cars handling and make it quite dangerous by changing things around, I suggest you search for suspension modification and do a quick 101 of the do's and dont's of suspension modification before you start swapping parts.

before i read your entire post i was going to say a bad wire arc to ground but a bad cap can do the same thing. hope this helps good luck

Usually a dead cell will show normal to low voltage on a voltmeter but it won't allow the car to start. I'm not sure on the electrical mechanics of it, but it has something to do with the battery not being able to run a return current through the starter when you're trying to start it. If the car will start up fine with jumper cables then the battery is most likely dead.

You need to warm up the engine, pull out the dipstick, wipe it off and reinsert. Pull it out once again and look to make sure the fluid level is sitting between the marked areas on the dipstick.

The best thing to do is go to any Advance or Auto Zone and buy the Chilton Repair book for this vehicle and it will have step by step instuctions for any repairs that you may need. It also has pictures too. They cost around 19.99 but this book is the best for any repairs that you may ever have. Hope this helps.

Open the rear diff cover you will see what is holding the axle in place.

If it has a sensor in the dashboard try replacing that

probably a worn out hinge, needs to go to a bodyshop.

check your wireing that goes from the vehical to the door,it will break wires in that harness over a period of time.

www.helmsinc.com. Should be about 10-11 bucks or try your local library.

possible u-joints going bad

remove panel, if any, check for loose wires, clean and lubicate 

passenger side under dash. Your going to find two clear vacuum hoses have been knocked lose "likely by someones feet." simply reconnect the vacuum hoses together . Problem solved.
The blower switch is controlled by a vacuum line..
let me know if this helps....

differential planet gears worn the thrust washers away,To confirm this drain the diff oil and check for any metal particles.Solution replace the diff.Good luck.

Check the oil filter adaptor bracket. My 1993 Safari had the same problem, and the adaptor bracket and seal were bad. Replacement fixed the leak.

You need to start by checking the fuse for your headlights (low beams). The DRL could be be bad, but I have not seen them go out very often.

This may be a Body Control Module (AKA, BCM) issue, this module controls these functions, wsaw this same issue on a Buick, it was the BCM, you will have to have an active system tester with live data stream cycle the locks to see what the problem is, as far as I know the dealer is the only place that has this type of dedicated test gear.
