I noticed today that there is a rigid hose going from the evap purge solenoid to the back of the distributor. It has a Schrader valve on it and looks like someone broke it before me and taped it together... Any idea what the part name is and where I can get one?? I'll try to put pics up later

 

The port is for testing the EVAP system. The black nylon line needs to be sealed, if it leaks you will get DTC's for the EVAP system. The line runs from the EVAP purge solenoid to a steel line near the rear of the intake manifold. If the line is broken, you could splice on a piece of rubber line that fits over the nylon and steel lines.

 

I have an evap system and heated o2 sensor B2S1 code. Do you think that would cause a low idle condition? I imagine its messing with the air/fuel ratio if the sensor is reading bad and I have a small vacuum leak. I've sprayed everything down and used including that line and didnt detect a leak even when I used propane. This thing has me beat. If after I replace these gaskets it isn't fixed I'm either selling it or paying the $500-900 a shop is going to charge to fix it

 

If the line leaks it will set a DTC for an EVAP leak when the EVAP monitor runs. When the purge valve opens, it could easily set a lean oxygen sensor DTC as well.
