Thanks so much for your continuing effert to help. No, there is no green vacuum line on this vehicle, its just a regular 3L V6 engine. It does however have the solenoid, and my husband has replaced that just the other day.
Again, thanks for all your input, its much appreciated.

well it might not be green in color but there has to be a vacuum line going to the egr valve otherwise how will it open?if there is no vacuum line attached to the egr valve then it will not open thus not fulfiilling its job of lowering nox.not having a line going to the egr valve might be your problem here.maybe it somehow got disconnected,find it and connect it to the egr valve.so as a final bit of advice, your egr valve needs a vacuum source so it can open properly( unless you have an electronic egr valve, which i seriously doubt a 92 ohv v6 taurus will have) SO FIND THAT VACUUM LINE AND CONNECT IT TO THE EGR VALVE.
