Steven, To be environmentally friendly the 02 ( Lambda ) circuit needs to be working. The hunting can be adjusted out very easy and the other problems will go away. You need a 3mm long handle allen wrench and call me for the procedure. You can also find it in the Technical Manuel.

To compensate the mixture control unit was adjusted. As a result the car idles smoothly and no longer hunts for an idle, but a side affect is that if I slowdown quickly (especially from moderate to high RPMs), like braking for a stop, the car will stall. I was told if I just reconnect the oxygen sensor, the mixture will be rich. What I need to know is it possible to reconnect the sensor and adjust the mixture with the appropriate allen wrench without any other special tools.
