Slow returning to Idle?
Has anyone experienced a very slow or lazy return to idle (800 or so RPM). After removing my foot from the accelerator the idle will solwly drop to about 1200-1300 RPM and stay there until I come to a complete stop. I can hear and feel the transmission flaring as it downshifts which is usually a symptom of high idle. Is there an aux air or idle valve that might be sticking or dirty. The local dealer tech says its "normal", I don't think so... does anyone have experience with this condition in a V,
