hmm ok well i know its not smoking now, to me it just doesn't make sense that if it were anything from the coils to the spark plugs it would do it after the car warms up, same with the fuel. but maybe thats just my lack of knowledge for cars. it lightly sputters at an idle but the intensity of it doesn't change at all when your in park and give it gas.

Heat can have an effect on electronics. Something you can try is spray a light mist of water on the wires, it will have to be kind of dark. Then watch for arching. This may help you locate problems.

Just a light mist. This works mainly for spark plug wires.

I know of a couple of problems these supercharged motors have. Either of them would cause a skip. One would be a fuel injector, the other would be a leaking intake manifold gasket. When it warms up and starts skipping, (if it skips at idle) spray some carb cleaner around where the intake manifold bolts to the cylinder heads. If this causes the motor to "perk up", then you've got a bad intake gasket. If it'* a bad injector, one cylinder will run lean, and you should notice that by looking at the spark plug. If you have the intake manifold gasket replaced, change the oil within a couple of days of having that work done. Many shops aren't very careful and I've had to replace several motors because they "spun a main bearing) immediately after having the intake gasket replaced because they allowed trash and metal slivers from using a wire brush to clean the old gasket off.
Good luck.
