You have to have the computer scanned for codes. Auto Zone will usually do it for free. Report back with what you find.

an 89 should be the 'paperclip method', find out which 2 terminals to touch together and you can read the codes yourself.

post those numbers here

I'm glad you were able to get it scanned but you may be a bit premature with your celebration. Oxygen sensors are usually just reporting a condition caused by another problem. The sensor is usually not to blame. That's why we asked you to post the code# so we could tell you what is happening. That guy at Auto Zone is nothing but a part time cashier and knows nothing about diagnosis. If the light comes back on, let us know what the code is before buying anything.

Low miles

from what I can see is you have low miles on a 89 you might want to make a pretty long road trip your engine will like that.You might just want to blow out the carbon as they used to say.Short trips are not good for an engine.You did say 28 thousand right?
Your O2 sensor might just not get cleaned by some good hot exaust flowing over it.
