ok, so I bought this very clean 97 GTP coupe long/short all options available in 97 and looks brand new and only 124 on the clock.
the engine would stall when stopped. not all the time, stalled only 4 times. i read around and saw that the fuel pump resistor could be the problem, when i removed the plenum cover, i noticed a lot of vaccum elbows broken and taped, or simply missing. so i did the vaccum lines over again and it is running better and the check engine light is gone...however.....i cant for the life of me figure out where one line goes, its from the evap emission canister purge vac 10mm vent port. see pic below. there are three ports. left/right and middle pointing up....where does the middle one go? i see an elbow off of it, but nothing else! cannot seem to find the line it goes to... anybody have experience with this or a good pic of the vacuum system that points this unit out? its behind the SC by the firewall

 


One is in.. one is out.. you likely have those. The last one had a 90 degree elbow on it from the factory, they did that to screw with us. It faces down when the valve is on the motor, why would it need a piece of hose? That's what GM did though. It's a vent or some crap like that. Leave it open.
 


I've never seen one. It surely can't hurt.. but I've run the thing without the elbow or anything on it and from experience..it didn't seem to make a bit of difference.
