Problem Description and Possible Solution
If the engine stalls after a cold start (the vehicle has been parked for a while), the idle air control (IAC) valve may be sticking. It may be fouled with carbon buildup. If cleaning the valve does not solve the problem, replacement will be needed.

Sometimes, I can not start the Tribute and after starting, it will die and come to a stop when slowing down at turns, stop signs or trafic light. It takes several tries to get it started again. I brought it in to a repair shop; however, they could not find any problem even afetr drivng it for two days and hooking it up to a computer. This sporatic problem has been going on for three months. I changed the fuel filter three times thinking that it was bad gas or trash in the fuel tank. The mechanic said that everything tested out okay on the computer with no problems with the fuel pump either. This problem is still tormenting me and my Tribute.
When the engine is cold, it start to fail, feels like of no have flow of fuel; after the engine reach the normal temperature it return to normal condition.
I have change many sensors also ECU, and the problem still happning
Have had everything from cold start, to sputtering, stalling while driving and completely refusing to restart upon stalling.
Computer, sensors, valves, gaskets, sparks and coils have all been changed in addition to a starter. The problem has yet to be resolved after two years! Once the suv is completely warmed, I have NO problems, but the check engine light remains on.
Engine is cold car starts fine but then get to a stop sign. When you take off it stalls - no power and check engine wrench shows up. Will not go in any gear. Stop car, cut off engine, give it a few minutes and then start car. Engine starts fine no check engine wrench and runs fine. Took to 2 mechanics and hooked up to a engine diagnostic machine. NO messages in memory!!!
Stalling when cold when foot taken off throttle. Starts again ok. UPDATE: Took off the IAC, cleaned out with some MAF cleaner and put back on. It's only stalled 3 times since then. It used to stall 90% of the time on start up. So IAC may be issue on some cars.
