They should be able to do a 95 since it has OBD II because all the connectors and codes are industry standardized. I think some stores say that because they don't really know what they are doing as well as not being able to do many OBD I imports. They should ask whether or not it is an OBD II system or not. In any case you can access the ECU in the front of the center console if you want to try to do it on you own.
I would pull the EGI fuse (under the hood) for the fuel pump and pull a spark plug out, reconnect the plug wire and ground the spark plug and try starting the car (or have someone do it for you) keep looking at the plug to inspect color and intensity of the spark. Reinstall the plug and the pump fuse, start the car and pull the connector off of the mass air flow meter (just after the air box) if the idle drops or the car stalls then it is working correctly.
For more info we need the codes to diagnose.
