Chevrolet Aveo, accelerates alone

Hello, how, I have a 2007 Aveo with the same problem, it accelerates cold or hot, sometimes if sometimes not, the IAC valve (for generic and original) is changed as four times, the cable that allows the passage of the air and the injectors were cleaned, I have taken it where 3 mechanics (including the one of the Chevrolet) and nothing, is fixed for a few weeks and returns again to accelerate in minimal Take it, I have thought it is the computer, help me please

You checked the oxygen sensor or catalyst may be ostrured
