Check Engine Light
Keeps coming on randomly. This morning whenever I started going it came on but when I hit my brakes and came to a stop it went off, it was also off on the highway. Can like autozone read a code after the light goes off? Also its a 94 so OBD1 right? I just drove all the way home and it never came on.

SN95's are OBD-I, you may want to run the DIY KOEO/KOER/Cylinder Balance Self-Tests

codes don't refer to sensors being bad all the time just that something has fallen out of spec and a component can be influenced to fall out of spec for various reasons....such as vaccum leaks, fuel preasure.ect ect.......

My book says:
176: heated exhaust gas oxygen sensor voltage signal indicates "lean" bank 2
189: heated exhaust gas oxygen sensor voltage signal not switching: indicates "lean" during part throttle engine operation bank 2
These mean?

sounds like you are running lean, or both 02 sensors are lazy. obd1 is less than accurate for code only diag, i would check for vacuum leaks and clean your maf sensor. if that doesnt work you may have bad o2s
