Being a A 000 means generally this part was used on several models different bodies, like 116 123 107 etc, and in this case I would venture to guess ANY 2.8 liter motor .
I was at a yard yesterday and probably saw a couple of them.
How about a photo of the part and the engine compartment.
Then I can find it more easily and help you out.

What does your smog check values say ?
High NOx or CO or HCs ??
Smog:
HC's were close, but passed at low RPM. (MAX: 191 / Measured: 191)
NO's passed at low RPM, (MAX: 1277, Measured: 1244) but failed at high RPM, (MAX: 1137, Measured: 1382)

I've attached an image of the one I found on eBay. This is exactly like mine.

In addition I took two pics of the EGR on my engine.

FYI: I called Dennis today, but he's closed on the weekends. (I was out of town for a while and a little under the weather when I returned.) Left a msg. Think I might peruse some junkyards later today, or tomorrow & see what I can turn up.
Thanks Again!!
