Hello, Everyone!
I have been getting a P0171 code every once in a while on my 1997 GTP and today while I was tracing vacuum lines I noticed there was a missing vacuum line on the bottom of the EVAP Canister Purge Switch. It has an elbow, but it goes to nothing. I put a cap on it and took it for a drive and my trims were sitting right around 0. Could this be the source of my vac leak? I didn't notice any noticeable vac from the elbow when I put my hand on it with the engine running, but should I? The part number for the part I'm looking at is 24506192 and it also says FASCO on it.
