The whole darn hose assembly came off while I was trying to unplug the upper end of it from the nipple on the top dead center of the rubber air duct at the inlet to the throttle body in prep for taking the duct off. Was taking the duct off to fix pinched wiring to the Throttle Position Sensor that I'm, except for figuring out this darn hose issue, 99 percent certain has been why my fuel gauge is whacked and I'm throwing codes P0122, P0425, and P1365 on my 2001 GP 3.1. Can't see anywhere it should go, nothing about it in my Haynes manual, no leads yet searching the GP forums. Seems like it might be an evap emissions canister purge suction line, but I cant see the canister, or anything else anywhere for it to connect to. Thinking of just leaving it off for now, and plugging up the nipple on the rubber air duct.
Little help anyone? I'm pretty good at herding miscreant electrons, but don't do plumbing very well. Not a lot of experience working on GM engines.
