Engine light comes frequently... 900 1995

That light almost surely does not indicate a fault in your ECM but rather indicates an engine fault elswhere that the ECM is detecting. It could be something simple and most likely is. It sounds as if the ECM is doing exactly what it is supposed to. Did the tech read and record the stored fault code or just do reset? If he did not read the code and discuss with you what it meant then find a new tech fast.

I am sure some techs would love to sell you a new ECM and at the same time fix some simple problem. He then has a spare ECM. I know this happens.

Auto Zone will read the OBDII code at no charge.
