2001 Mercury Sable Question: engine hesitation at idle especially when i have the heat or ac on

I cannot tell which engine you have, so I am not entirely certain how to respond. However, if you have the 3.0L OHV engine, you could have issues with the valves in your heads. A compression test is in order, perhaps. You could also have injector issues.
