Default Another EGR question for experts ;)

Hi guys!
i have a question about elimminating the EGR,i placed the hooker headers on my car,i took off the A.I.R. system,and used the eliminator bracket,but i tried to take off the EGR stuff,my headers doesnt have the EGR,i caped the EGR hose from the manifold and i don't know what else to do,do i have to disconnect something else?????
i can't find a post showing or telling what else to do about it.

His '91 didn't have the EGR Sw as did the '85-'89 but it does have the EGR Valve & EGR Sol.

It will eventually send a Code 32, but mine only does it on extended hwy use at higher engine temps. I just yanked the EGR and left the green wire sitting there disconnected. On my website is a page that talks about deleting it.
