I don't have an early charcoal canister handy. If you think there's a leak in the area it seems you could block the vacuum lines and see if it fixes the drivability issue. Do you have a check valve in the line to the vacuum reservoir? I've generally put one there because the reservoir valve gets weak with age. Have you searched for past posts re: 85T idle issues on this board? The 85T ECU had a history of poor idle on cold start. It was common to replace that ECU with a 87-88T. From my ancient memory the problem 85T ECU is --- --- 515. The later one is --- --- 538. Do a search on that to get a consensus from our past experts.
