You buy a new egr valve for about $300.00 or take the old one apart and clean it. It fixed my 1990 3800 lesabre.
I had the same problem with a 1992 Park Avenue with the 3800 engine. I first replaced the electronic ignition but that did not fix the problem. I then replaced the crankshaft heat sensor. That fixed my problem.
The contacts between the speedometer head and the wiring connector need to be cleaned. If that does not work get a used speedometer. It fixed mine.

Just yank-out the fuse for the horn until you get it fixed.
The check engine light comes on in a car when there is a problem with the engine. It will go off or be reset when the problem is fixed.
The abs light is on because there is a problem with the system. It will remain on until the problem is fixed. Once the problem is fixed it will reset itself after it is driven.
