How such, I have a 2006 2.2 Malibu 2.2 of 4 cylinders, I have a failure for several months and I can't find it, my car turns it on and lights perfectly, after a few seconds the low -go -up revolutions head and the engine heads for a moment, suddenly the revolution I turn off the car does it again when it starts again but only once, after normalizing the car works perfectly. I have already done the following: Wash the acceleration body, change the TPS accelerator position sensor, change oxygen sensors, and nothing, I am desperate, to see if anyone knows what may be happening, try to impose the IAC valve but I do not find where it is, nothing else I find it
