Try pulling the code from the ECM to see what it is indicating. Replacing the EGR valve may only have been part of the problem. O2 sensors typically last 50-60k miles so in a '95, it should be about time to replace them. Before you do this, though, get an OBD-I compatible code scanner to tell you what the problem is.

Autozone, or Advance, may be able to scan your ECM for free, and spit out a slip of paper telling you about your problem and what to do with it...... Optionally you can get a Haynes manual (recommended), it will tell you how to read the codes yourself, and it has a list of all the codes, and what they mean. BUT!..... 1995 is the only year GM produced a Hybrid OBD system in some cars: OBD- 1.5. If your diagnostic connector does not have a "B" wire (and only an "M" wire, with a purple wire 2 spaces over), then, unless Autozone, Advance, or friendly mechanic has the right scan tool, you may need to go to a dealer to get your codes scanned... but it will probably cost you. Here are a couple of Important notes:..... NOTE: Some 94 & 95 models do not have the B terminal. In which case a scanner is required...... NOTE: Some 94 & 95 models that DO have the A & B terminals still require a scanner...... All vehicles after 96 are OBDII, and require a scanner to access them...... Here's a Video you can watch which may be helpful (if you have a "B" wire on your diagnostic connector, and the OBD-I system...... http://www.youtube.com/watch?v=V8nZpQyoRh4
