Question about 1999 Ford Taurus
It runs fine while engine is cold but once the engine is warm and you go to slow down or go to take off the car starts running rough and acts like the engine is going to die. But once you get the speed up it seems to run ok.
your problem appears to be the idle control motor located on the air intake manifold it is a small motor that goes bad quite often. Other items that can cause this is a bad /clogged air filter or a tune up (spark plugs and wires), or clogged fuel injectors. to clean the injectors you can buy a container of fuel system cleaner and pour it into the gas tank and as you drive it cleans the system.
Once the fuel system is cleaned via a tankful of cleaner & gas then the idle controller motor would be next on the list to be replaced.
Good Luck !
