You have a head gasket that has blown out. IT is letting coolant into the cylinders and that is what is causing the steam out of the exhaust.

Changed spark plugs now runs rough and has thick white exhaust


Changing the plugs probably had nothing to do with it.
White smoke is usually a sign the engine is burning coolant or trans fluid. You might want to check those fluid levels.
If the coolant is low, you may have a leaking head gasket or intake gasket.

ROUGH IDLE,WET SPARKPLUGS,KILLS


The Symptoms tell me it is a head gasket. A leaky or bad head gasket would cause all of the problems that you mentioned.

Burning water causes White Smoke, Burning Oil causes Black Smoke. The oil and water are mixing with the gas in the cylinders and causing it to run bad. Pull out the dipstick and look at the oil on it. Does it look like good oil? Or does it look watery and or foamy or grey colored. Open up the radiator and look inside, do you see oil?

This seems almost text book to me... I would have someone local to you to have a look at it to be sure.
