Its not just the setting, but how you set it. If you want any electronic-BBD-equipped AMC to run correctly, you need to set everything at the same time per the IS-12 procedure (so everything interacts properly with everything else, carb dist, smog junk). Of course this assumes everything is working correctly (EGR, BBD idle bleeds not plugged up, vac hoses OK, etc.). I'll send you a .pdf copy of the IS-12 in a separate email (since the list doesn't allow attachments). Its the Eagle version; but same process for Concords. Anyone else wants a copy, send me a request.
