Checked everything and still same problem. Changed the Idle Air Control valve and and that was the trick, everything is OK and running fine. Only now the car idles at only at 650 rpm. When replacing the valve I didn't have a tape measurer to get the proper extension. I just extended the cone to match the old IAC valves length. Does the length really make that much difference. Should I go back and make sure that is extended no more than suggested 1 1/8 length?
