white smoke and rough idle

any idea what would cause white smoke coming from the exhaust, and the car to run real rough?

thanks

sounds like you’re burning coolant. maybe a blown headgasket or crack head. that could also be why your car is running rough too.

thanks, its actually not my car, but a car I am thinking about buying, Im trying to figure how much work it will need.

kewl no problem.

unless you’re talking about the little steam that comes out the tailpipe in the morning when it’s warming up and goes away, thats normal.

Your rough idle might be solved with a new rotor in the distributer cap. Worked on my friends bimma. Its like 10 bucks for our car
