Map sensor and round part on manifold
found a transmission part, it was like a ring, then had to slice a small notch in it. then dropped it down in the intake, and used something to push it down. there are tangs on the inside that have to be squeezed in to get that plug out. if you need pics, i think i still have it laying around. it needs to be just the right diameter.
but like i said, you cant buy a new one, so its only useful if you have a new plug to put in, or need the plug out to do some repair
