I could be wrong here but theres a chance the back pressure in the system changed and the sensors are sensing that.. triggering the SES light..what code are you getting with the light? Maybe if you can get that info Kyle is pretty good with the codes for these trucks..

You may have a fun time getting the codes read. If you have the OBD1 connector, then you may be able to do a simple paper clip trick and watch the check engine light. It will blink out the code. Refer to TroubleCodes.net for the code descriptions as well as a picture of what an OBD1 diagnostic port looks like. As the link above suggests though, some 95 blazers may not be able to be checked with out the proper scan tool. Most autoparts stores do not have the proper scan tool for checking these intermediary PCMs that were used in this year only.
If you have the OBD2 diagnostic port, then good luck getting the codes read.
The DLC is located under the driver side dash.
