My truck goes out in low revolutions

Hello Friends of the Miren forum I have a little one but very annoying problem that is the following:
I have a Ford Explorer 93 that at the time of turning it if I do not accelerate it and after keeping it accelerated a few seconds when you release the accelerator it remains but I put the change (it is automatic
) Well a week and the failure turned and makes a couple of days clean with carbuclean the acceleration body but followed the fault ... what else can it be?

Hello partner, you did well to clean the acceleration body, I do not know if you included the IAC valve, which is close to the acceleration body, said valve controls you the RPM and is the cause of the engine to turn off or accelerate too much.
When dusting mixed with vapors d oil and gasoline dirty the vastago of the IAC valve, for that you must give it minimal maintenance every 6 months.
The valve has 2 5/16 screws
you withdraw, once outside the bottom you will observe 2 Horificios, you have to add Thiner or if you have the possibility of getting carbucleaner (it is a pressurized boat that is used to wash the carburetors)
with the help of a small dramator, it gently moves the one in repeated occasions until you see the ribbing clean, make sure you make sure that.
Once the operation is performed, it torque with compressed air.
Install the valve.
And ready.
Greetings.
