I have had a hunting idle issue for years now. I have drivin the car with out the idle stablizer sinse it started. I have replaced the idle control valve with a good one twice and it still does the same thing. I have even tried to reset the idle by jumpering the ports on the test plug but it seems to not do anything. If im not mistaken, when jumping the test plug the idle controller should lock into position and not try to control the idle. But it just keeps opening and closing raising and dropping the idle. Any help would be GREAT! Thank you.
