I fixed my "Black Smoke at idle" problem !

It was some kinda breather pipe or something that had come loose.

It seems to fall off again real easy though. I suppose I need to replace the Y shaped plastic pipe connector thingy. Anyone know what it's correctly called? I'd have to get it from me local Toyota dealer, right?

I would sort that ASAP as that pipe goes to the fuel pressure regulator, quite an essential piece of kit.

 

It sounds like you have been running extremely rich at idle which would be due to this pipe being disconnected. Your fuelling will be all over the show.

In that case IMHO i wouldn't boost until you have it fixed up properly. Not worth the chance of buggering your engine.
