Well, I think I spoke too soon about the relay. I did not get a definitive test with the wagon relay in the sedan. I also jumped to conclusions when the sedan relay did not immediately turn on the motor. I went on an errand, and just for fun I hooked up the scanner when I returned. I noticed that the secondary air monitor was set! It must have actually been a bad relay. I have not had a chance to test the sedan yet. I will try to start it in the morning when it is cold. I suspect the secondary air pump will NOT go on. At any rate, I am happy to be done with this issue. Thanks to all that helped. I learn a lot from the folks on this site.......Rich
