Electrical problems.. yay!

If its running, go around and wiggle all the wires and hopefully it will stop running.

So a little update.. I drove the car and noticed the "chugging" my wife was talking about. It starts at about 35mph through 50mph when I'm barely giving it any gas. If I power through it, it goes away. So I decided to clean the MAF, TB, change the plug wires (plus were done earlier) and clean my grounding connections. Tops of the coil pack towers were clean, no cracks that I saw.
Took it for a drive and it is still doing the same. It seems to do it after heavy traffic (maybe heat related?). Anything else I should check guys n gals?
