Youre a bunch of beast . I was pretty sure it was 90 but I didn't said it because I wanted neutral opinion. As for the ISC, I changed it because I though it was dead.
YOUR REALLY GOOD GUYS

I had idle issues and I think I discovered the origin. I plugged the 2 nipple at the top together with a tube (I didn't need them). But I discovered that both nipple were leading to hole inside the TB. Each of these holes were the opposite site of the throttle plate which was certainly leading to air bypassing it .

Anybody knows where were those nipple connected to and if my theory is good.

, the other day edwin was looking in my engine bay and saw my throttle body and said, "O, you have a 90?" even though I have that fatty, out of place cruise control which was right next to where he was standing. Some people just know whats important, and what isn't, like the location of the four vac sources on our throttle bodies.
