OK so I own an '84 GSL-SE. I have a huge problem with cold starts.
When I start the car it likes to shoot a bellowing white cloud out of my exhaust continuously until the car warms up and then no problem.
I'm guessing i have some kind of coolant seal issue because there is no more white smoke once the engine is up to temperature. The seal is much better then. I would like to know a reason for this and a possible fix for my problem.
Also while driving the car once i get to or past 3k rpm it likes to stutter.
Lets say if I were to be driving in second get completely off of the clutch and floor it, Nothing happens.

I have no idea what is wrong with it at this point. everything up until around 3k is fine but not there after.
The car has 150,000 miles. Aftermarket intake and RB headers and no air pump if that can give any kind of problems.
Thanks in advance.
