it's hard to tell by the pics but it looks like either the vaccume booster hose or the pcv system hose, im leaning to the latter, but it looks like its blocked so i wouldn't think thats whats causing your bad milage.

or just block egr off those cars realy liked there antibackfire valve i whould reinstall one if you can find it the stock carb setup worked realy good but had a ton of stuff hooked to it. The fact that it has a code means is a feedback carb theese carbs had a varablle main jet that was computer controled and tended to get stuck in one spot mostly on the ritch side. It has default abillity can go full ritch if sees a problem. I whould serch out a 85 -86 carb thats non feedback and try that.
