Thanks for the replys, I didn't even think to look for a PN on the part itself, this is what I found: 123-300-05-33. I tired the number here but nothing worked, I tried with the spaces and with out.

About the transmission vacuum part, I don't know if its that or not. Mine has 4 ports, 2 top and 2 bottom, they are labled. TOP: 1, VAC 2, EGR BOTTOM: 1, Atm, 2, VCV. Also, there are 2 valve looking items beside the main part, and they have hoses (and eletrical plugs, but the main part has no elc. conections) that also run into the main part and else where (hoses go into conduit, and can't trace) So maybe this will help.
Thanks

Randy
