Whats up guys,

Car is an S13 powered by a CA18DET. I have had a fuel injector leaking a little drip of fuel onto the block because of a bad o-ring that I haven't had time to get replaced. I drive the car only once a week anyways so I was planning on getting the o-rings changed sometime soon, just not immediately.

Anyways, last night I am out for a drive and notice a little bit of smoke coming from under the hood, not a big deal, I know it's that little drip of fuel burning up. I drive around 10km more and trouble starts. I notice more smoke coming from under the hood. I check my rear view mirror and the car is literally blowing CLOUDS of black smoke out even at idle. It is just puffing and puffing it out.

I stop the car. I pop the hood and there is tons of smoke coming from the injector that was leaking fuel out of the o-ring. The car starts but does NOT have any power at low RPM. I can barely move it. I had to give it a fair bit of gas just to be able to park it in a proper spot. It stalls SUPER easy if I don't give it tons of gas and even then it moves slowly.

I can understand the smoke under the hood as a result of the o-ring possibly giving up at this point. But why is there TONS of black smoke coming out the rear? Also, why no power at low RPM? It stalls out if I don't give it TONS of gas.

Whats the best thing to do here? I am worried about doing any serious damage to the engine. I know I need to change the rings to fix the leak but now I am curious as to why the car barely wants to move. Does the no power at low rpm give any hint of serious problems?

Any advice/info would be appreciated.
