I have a 2005 Expedition that keeps stalling. I have already replaced the cam shaft sensors and the throttle sensor but yet it keeps stalling out mostly at low speeds. I thought it might be an idle air sensor but could not find one, I dont think this car has one. What eles could it be?

Any known diagnostic trouble codes? Remove the inlet air tube from the Electronic Throttle Body (ETB). Using a suitable cleaner and brush, (an old tooth brushworks ok) clean the throttle bore and plate as needed, disconnect the battery negative cable while cleaning the throttle body so that the PCM's adaptive memory will clear. Then recheck the condition

the only codes I got where for the cam shaft and the throttle...could it be the mass air flow sensor or bad oxygen sensors causing the stalling? It only seems to happen when going slow such as from a parking space after going in reverse or in a turn

no the stalling acures when the foot is on the accelarator but when slowing and turning sometimes sharply around a turn
