Well here is the story. Car drove fine to school even ran idle in the parking lot for a few minutes after I got there. I go to leave school and start my car as usual and it will barely even run. Idle is erratic anywhere from 300-1500, along with vacuum surging from 15-22 InHg. The car stutters under any load whatsoever, it dumps white smoke out of the exhaust after small revs or attempts to idle it myself. Black smoke pours out upon start up. Oil is fine, radiator is full, overflow bottle is normal level. Just need some general feedback or direction. My first instincts were head gasket since it is dumping so much white smoke, but the radiator is fine along with the oil. Nick just helped me replace the lim gaskets a month or so ago so i can't really imagine them failing, especially in a span of three hours in the parking lot. Anyway here is a video, just wanted to hear some opinions. Mods are in my signature, currently running just a 3.4 on an extremely conservative tune with 12* wot timing. Runs a tad rich normally. Here's the video of my sweet cam sounding pos.
