Message Ohm the injectors to be sure. If memory serves, brand new injectors should ohm out to 12.5k ohms. An open circuit means the injector has fail completely.
If your injectors have failed, typically what happens is the 02's detect a crap 02/fuel ratio, and dump more fuel to compensate, resulting in an extremely rich scenario. This exact thing happened to me. I had literal gas shooting out the back of my exhaust.

Also, check sparkplugs, coil packs/coil pack connections. A bad spark will do the same.

Lastly, check 02's. There's a million tuts out there on testing them.

Good luck.
