Slow shut off without ACC/Normal shut off with ACC
I noticed that it's taking a few seconds for the motor on my 85 300 tdt to shut off only when the ACC is shut off completely. Otherwise, with it on, it shuts off fine. I recently replaced the center vent vacuum actuator and the others checked out OK. Any initial thoughts before I get out the vacuum gauge and forceps?
Thanks

Bad switchover valve, leaks only in the OFF position, OR low vac in general, but the drag from the AC stops the engine faster with the ACC on.
