Egr diagnostic issues

Craby I pulled the ecm and the ground wire was still grounded. So there is no doubt a short in that wire?
Also, I had a spare ecm from a 96 camaro, put it in just out of curiosity.
Still seemed to idle rough. drove for about 5 or 10 miles and no SES light.
Headlights and interior lights dimmed and flickered slightly.
Going to put the original back in tomorrow just to be safe.

looks like the evap canister purge solonoid is on that line as is the cooling fan relay. try unpluging the fan relay or the purge solonoid and see if that clears the ground
