sounds to me liek a vac or dashpot issue, there are a series ov vac activated dashpots under the dash near the drivers fotwell above the trans tunnel, they regulate the flow of air and are fed vacume by 2 vac lines that enter the passanger compartment near the battery, it's a pretty common problem, either the hoses harden and crack ro break or the dashpots stick or harden and crack or break
and that noise behind your bumper is likely a vacume pump
and I'm not sure what the dealer is calling an "air canister" are they talking about the vac canister?
