Ford Explorer V6 goes out

Hello, I appreciate your time and help in advance.
I have a Ford Explorer Mod 96 with V6 and the problem is that the engine always turns off at the time one wants to stop on a street, at the time the clutch squeezes, the engine stops instead of being regulated. He only does it in those situations when one wants to stop the vehicle, then accelerate and climb the low revolution engine until it remains regulating when the clutch is squeezed. Regulates triggered and the IAC is changed. I read that to know if there is a false air input, at the time of electrically disconnecting the IAC the engine must stop and does not do so there must be a false air in airpero I do not know where. Another thing, velocimetro does not go but before this problem. Thank you very much !!

Not necessary if you disconnect the IAC the engine stops, it can be accelerated, you should check it in the Scaner because this valve works together, with the MAF or MAP Air flow, check the pressure of the gasoline pump, filter, it goes out because or does not have gasoline or there is no spark to burn the fuel, the velocimeter of transmission, if this is working correctly, it could be the board, frequent, the oxygen sensor sockets are dirty

hahaha The oxygen sensor has nothing to do with velocimetro and much less is located in the transmission, what a good joke !!!

Sorry is the speed sensor,

Hello, thank you very much for the answer. That spark is missing I am sure that since at the time it goes out, I start the engine with the inertia of the vehicle and start the most and stay regulating after that. It can be fuel, but I don't know exactly.
