hi just after buying a 97 glanza v and it is running at a very high idle even when warm it varies from about 1500-1800rpm any ideas where to start there's also some sort of greddy boost settings on it not quite sure how it works but two pipes from it go to the turbo actuater and one to the inlet manifold and there's a fitting for a pipe on the bottom of the unit with nothing on it anyone got anything that sounds like this with a bit of info on it!
