993 high idle question

[johnkszabo]

Hi everyone just finishing up a project car, a 78 SC with a 1995 993 Non-Varioram engine. The car runs great but we cannot get the idle down from 2800 RPM. Any ideas what what might be causing this. We have double checked all electrical wiring and connections. Any ideas? Thanks in advance John Szabo
