so your saying that there is a leak somewhere after the TB?

Only way to really find the leak is by spraying carb cleaner or propane gas at different places and see if the idle changes "significantly".

That part in bold sounds like a REALLY bad idea to me. I've never seen this suggested before.

That is actually the method of choice for most mechanics as it doesn't leave as much residue.

I used Berrymans or Gumout spray to hunt for leaks. That's how I found the ones in the vacuum ports on top and the EGR valve. The idle will jump a little. That slime you see is EGR/PCV gunk.
