Don't worry, if you don't know something, the only way to find out is to ask.

The engine should be running... Yes, the rest of the procedure should be the same as has been mentioned on here.

Pouring it in via the throttle body is just something I did...It might be mentioned before on here, but I haven't seen it. The reason I say it's more controlled is the PCV will take it right in past the blades, which is why you have to be even more careful about pouring it in slowly. It's also just physically easier than getting it into a vacuum hose. I hold the throttle arm just slightly so it revs a wee bit. That way, I can pour a little more without stalling it. The only time the engine should be off when doing this is letting it soak after it stalls or you turn it off for that purpose.

The reason you don't want to pour too fast is hydrolocking the engine. On the intake stroke, the intake valve opens, and it sucks in air, and if you're pouring it in, GM TEC or whatever... Then both valves close, and the compression stroke occurs. If there's too much liquid in the combustion chamber at this time, it will try to compress the air/fuel mix and because liquids don't really compress, it will be unable to do so, and that can cause some nasty engine damage. Instructions indicate you can pour most of it in...then pour the rest in just enough to stall it... That way, it cooks the carbon off as it sits in there. I've always chickened out on actually stalling it lol..but that's what I meant by be aware of hydrolocking whenever you're introducing any liquid into the engine.
