I'm going to take a wild stab here and guess that your engine is actually running when you do this?
Seriously, a small amount of smoke doesn't mean it's over ... unless it's coming out of your nose and you aren't holding a cigarette.
If the smoke is blue, it's either a Ford or it's burning a little oil.
If the smoke is white, your injectors might be sticking and it's overfuelled.
If the smoke is black, there's a rich spot, generally not much to worry about in terms of operation, but it is wasting fuel, polluting the air and not running as efficiently as it could.
If the smoke is brown with green dots, pass whatever you're smoking around a bit because the rest of us want some!
