I have a problem with my vocho I turn it on and it goes well as soon as a time passes and it stays accelerated I turn it off I turn it on and it works normal again a while goes by and it accelerates again and I changed the valve iac, oxygen sensor, tps, temperature and keep doing what they recommend me ??

Probably the IAC valve, if you changed it check that it is not the metallic one, that is of golf not of Vocho, it works in another range and does that of accelerating, it is not true that they carry the same, the ducts through which the air passes are of different size. The original VDO brand is very expensive, but I think there are not so expensive options.
