I have a 2004 Subaru double overhead came turbo motor with the Link G4+Storm Blue model and I having issue with the idle. When cold the rpm sky Rockets to 2500 rpm+ and won’t come down to a reasonable idle speed. I have a 6 pin idle air control valve which I’ve switched out to hopefully resolving the high rpm and it hasn’t. I would appreciate some in-site here to help resolve this issue.
thank you
Mike
