Because the CO adjustment is critical to good operation, I suggest you have the CO adjusted at a smog station when the car is at operating temperature. Then leave it alone and work on the other parts of the CIS system. I had to add a 5 ohm 5 watt resistor in the Warm-up regulator wiring so the regulator take a longer time to bring the idle down to normal. The car should idle at about 1200-1500 rpm at start-up and drop to 900-1000 rpm warm.
