Ok so I have a 2nd gen integra and am having the following problems:

-On start up white smoke and it has trouble starting up like it hesitates to catch itself

-Once warmed up it dies most of the time when at idle (its a 5-speed)

History on the car: Was overheating BAD, as in the car would stop running overheating. Fixed that it was a water leak at the coolant tube on the back of the motor. Now the car occasionally gets hot at idle but instantly cools down when I drive again. I think this is the radiator from what I've been reading?? Could someone please help. This car is pissing me off.
