Unhappy Vapor Bariers/Air Barriers????

What's the latest research suggest? I have seen conflicting info on this subject in the past. I live in Michigan and 10 yrs ago we installed foil-backed foam board on the exterior AND wrapped the interior w/ 6ml plastic-oops!

Which material to use and on what side of the wall???? Would be in a northern climate with nat. gas forced air heat.

Anyone know? Thanks, Sparkie
