Oldsmobile/Buick Repair: Reset check engine Button for Oldsmobile, oxygen sensor, engine button

Question
Where is the check engine reset button found on a 1996 eighty-eight oldsmobile?

Answer
Go to Autozone, have them read the codes for you, and reset it.
A scan tool is needed, and they will do it for free.
Keep the codes, so you have an idea what to work on, but keep in mind that a rich or lean oxygen sensor code, does NOT necessarily mean you need an oxygen sensor. You need to repair the problem that caused that sensor to read that.  Same goes for many of the other codes, and they will probably come back, until the cause is corrected.
