I'm looking for a COS processor from a 90 SC with auto trans, non egr. Needs to be in good working condition.

What do you mean by a cos processor? What is it for I probably know what you mean by a different name.I have a 91 auto parts car and may have what you need. Let me know.:confused:

I think it's the eec, but it's got to be from a 90 model from what I was told.
I've got an 89 that I'm deleting the egr on and the check engine light will be since the egr harness will be unplugged. The 90 didn't have egr, so the processor won't be looking for it and no check engine light. I don't think the later model processors will work.

check with your local dealer or salvage yard if this part # will interchange sometimes a year one way or another will work properly the # is F1SF-18B008-AA if this will help pm me.

I think 89 and 90 are 2 digit codes and 91 and up are 3 digit, so I don't think a newer one will work.
