This may sound crazy but I was having idle problems from driving and when I come to a complete stop the idle would bounce around 900-1500 and after bouncing about 5 times it would settle down.
It was doing this for years and one day I just got bored and played with the commander and turned the O2 controller in the ON position.... and it fixed that problem right away!!!!~~~~ It seems to bounce every now and then when the O2 sensor is cold...like in the mornings...but once its starts working then it fixed my idle problem~~~~
Just wanted to share the wealth and can you guys try it to and verify if that works or not?
thanks
