'92 Buick LeSabre, V6 3.8L

I posted here months ago when I had stalling problems with my car. Fixed those problems, but now I have some new issues.

Check engine light started to come on every now and again, but would go off right away. Then, after some time, it comes on a lot and usually stays on. The car IS overdue for an oil change, but that wouldnt make the SES light come on.

Plugs and wires are about a year and a half old, and yesterday it started misfiring, so I discovered that one plug or wire is bad.

Would bad wires/plugs make the SES light come on?

my father says he thinks it could be a bad O2 sensor causing the SES light to come and go, and the light was coming on a few weeks before the plug or wire incident occured.

Check this site. It shows how to get codes and the meaning of them.

Being way2old is why I need help from younger minds

well, I did some simple stuff today. Replaced plugs and wires, problem remains. Traced it back to a single post on the coil pack. Going to try to get a used one tomorrow and hopefully this fixes it. Darn coil pack/ignition module!!! I guess it's finally dying.....

well I fixed my stalling/misfiring problem with a new coil pack.

i did try to do my own diagnostic check with a paperclip, but it didnt seem to work. Going to change oil and maybe trans fluid, oil/fuel/air filters.
