Question about 2003 Lincoln Aviator
You probably have a vacuum leak. I had this same problem and it is a $20 part that takes 5 minutes to replace. Open your hood and listen for a high pitch sucking or whistling sound. My vacuum leaks were around the back center of the engine on a rubber elbow that connected to the PCV valve. Then a year later the other rubber elbow went bad that connected near the back of the intake manifold.
