Stumbles and dies, smoking cat [VIDEO]

[99SHOtime]

My car is having a problem and I can't even drive it it is so bad right now.

Basically what is happening is I start the car, it sounds fine for a second or two, and then when it settles, it just starts stumbling and dies. If I rev it to keep it alive it shutters a bit (look at the video below). There is a liquid on the bank 1 cat which is causing it to smoke, but I don't know what it is or if that is even the problem.

I am also getting a code for: "Not enough H2O's to Bank 1 Sensor 1 and Bank 1 Sensor 2" --- but I don't know what this means?

I have tried replacing the MAF, doesn't work, and the IAC is fine.

Any ideas?

What are the actual code #s?

I would guess O2 sensors for a start...bad plugs or coils possibly.

It's not O2s as the car can run without them, not well but will at least idle. Maybe a vacuum leak? Or clogged cats?

I was thinking more towards a clogged cat as well. I am going to take a look and see what happens!

Thanks guys

I don't think it's a vacuum leak as it was running fine before this, but a clogged cat seems to be the mot reasonable answer.

For what it is worth, that sounds to me like a back pressure ****, so I also would without more information guess a plugged cat. likely the one on the y pipe on the bank 1 side, from your code info.

Remove the y-pipe and let er rip to see if it will run. You'll be deaf afterwards, but up until then, it'll sound AMAZING.

The only other thing would be a massive vacuum leak, I think.

No, it will just sound unbearably loud. Bring down every policeman within 20 miles loud.
