ok well as most of u probably have either had or currently have an idling problem, so here it goes.. once i start my car it stays at a steady 800 rpm, but after a few mins it begins to jump around and eventually to the point of stalling out... so my question is what can the problem be.. i replaced the idle control valve.. is it a vacuum leak, timing? or i heard it could be the throttle body in which would i possibly need a new throttle body to keep a perfect idle? this is pretty much the last issue with my stang b/c i have had a heating problem for quite some time, by replacing the fan, radiator and thermostat, that managed to fix the over heating, now comes the idle problem, so help would be excellent please!!
