While checking my hoses, I pulled the one coming off of the crossover tube which leads to the IACV and what looks like a bigger version of my boost calibration jets fell out of the hose. I looked on the Courtesy microfiche and don't see this jet in the air circuit, and I'm wondering if it belongs there and what it does. Could be someone worked on the car and put this thing in by mistake? If so, where is it supposed to go?
