From running rich due to a bad ecu, 30 miles = 9 gallon, and puffing smoke like a coal train, it was also foiling the new plugs causing it not to start.

After getting a replacement ecu, it was puffing a little and would die as soon as it went above 3k rpms.

So I poured about a glass of water in a vacuum hose and had the engine run at 4k rpms. It worked, o2 sensor is fine and it blew out chunks of crap. And there is a decent amount of exhaust air coming out of the tail pipe.
