That is called dieseling...I agree with what Ede said about the tune-up and timing adjustment. When was the last time you did a tune-up on the car?

a 91 dieseling? i would think that if its carbed, if its TBI or TPI & dieseling you have a fuel leak into the engine. if its not dieseling but runs normally for those 10 - 15 seconds after you turn the key off, unhook the cooling fans & see if that stops it.
if you are carbed & are dieseling, then what ede & 91GTA said applies & also check your base idle speed.

Yeah I'd say 10-15 seconds is a lot for it to be "dieseling"
Like mentioned above, unplug the cooling fans and see if it still does it.
