Hi: I am not quite sure what you have done here. If you want to do this "by hand" do an augmented regression: http://www.stata.com/support/faqs/stat/endogeneity.html

ivreg2 y (x = z), endog(x). Or do the usual hausman test via Stata, e.g., reg y x est store one ivregress 2sls y (x=z) est store two hausman one two

sem (y<-x) (x<-z), cov(e.y*e.x)
