AFTER NEW ,PLUGS,CAP,ROTOR,IDLE CONTROL VALVE MY 1990 300CE STILL DOES NOT IDLE .IT IDLES BELOW 500RPM WHEN THE A/C IS ON AND WHEN THE A/C IS NOT ON IT STILL IDLES VERY LOW. EVEN IF I DRIVE IT FOR A HOUR OR MORE IN STOP IN GO TRAFFIC IT STILL IDLES LOW. IS THERE SOMETHING ELES IM NOT CHANGING TO FIX THIS PROBLEM? IS THE IDLE ON THIS CAR CONTROLED BY THE COMPUTOR?

The over-voltage relay powers the whole system up. Without it, nothing happens. Also, the control unit for the fuel injection does control idle speed.
