Cold start, idles at 1,000, then drops after a minute or so to about 750. I pulled the connector while engine still relatively cold, and the idle surged up to 1,000 again. Plugged it back in and it drops to 750. Still minor hunting/surging. However, unplugging the ICV when the engine is warmed up seems to have no effect. Normal?
