Moved the ground to a threaded hole in the thermostat housing, started car, started off at 1100 rpm then after about 20 seconds, the aav closed and brought the idle down to normal. What a workout, I have a lot of experiance in the mechanical field but a couple hours here and there at night makes it difficult when working a full time job. I have had a lot of suggestions to check the aav and bought two others to try to swap out. I guess when I had voltage to the valve, I was right, but I had no ground. This car would idle as high as 1500 rpm and surge. Glad thats over. Well now its on to the next project. Thanks for everyones help. Bill.
