KlausC,

Thanks for the link. I believe it confirms my suspicions, and I quote.

''The ECM will operate the purge valve after idling for a brief time when the engine is in closed loop.
ECM will operate valve at a low percentage initially and the fuel trim correction will be paused so the oxygen sensor can be used as an indicator of whether there are vapors in canister or not. Rich indicated by sensor will cause ECM to continue to operate the purge valve for 40 seconds +/- , lean indication will stop purge for a time until ECM repeats canister monitor. Canister monitor continues while idling and whenever vapors are detected purging will commence.
Purge valve should be sealed until ECM provides ground. Purge valve is provided 12V feed whenever injectors and other components of fuel system are powered.
The canister vent is controlled through a canister vent closing valve. Vent is opened except when vapor loss testing is going on.''

On initial start up the ECM keeps the purge valve closed because you are running open loop. While driving it may nor may not open it. Bottom line, it depends.

However, once you are closed loop, and come to a stop and idle, the valve will be opened to drop the fuel rail pressure so that the O2 sensor does not detect a rich condition. This is where I have screwed up. On the brand new sensor I only tested in on cold start up not knowing what I know now, so I now have another brand new sensor coming to replace my original to the car one. If this does not fix it, then I have two options: 1) buy a three day subscription to Vida and find the troubleshooting steps so that I can walk through this properly, or 2) pay the man to find the real problem and suck up the cost. Not sure what I'll do when I get there, but at least I have options, and options are always good to have.

Thanks again,

Matt
