Exhaust Emissions

Hi All,

I've been working on replacing the sensors in my 75 450SE. I changed the coolant temperature sensor and now I get lots of white smoke on a cold start on a cold day and a really heavy exhaust stink from the tailpipe. Do I need to make adjustments of the air/ fuel mixture after changing sensors?  What would cause the exhaust to smell so bad?
