Today, Helga started idling at 11-1400 RPM at unloaded idle. I lightly rapped on the Idle Air Valve, and the idle returned to 700, but as soon as I would goose the throttle, it was back to a fast Idle again. I suppose I'll be cleaning the IAC vavle tonight. Does anyone have any other thoughts on the issue? Intake Gasket is fresh (this summer) and the TB was cleaned and set at the same time. No vacuum leaks (that I can hear), and as I said, this just started occurring.
