Sorry, I meant to say richen the mixture not lean it out further.

In either case, I tried both, none did a thing to the lambda control.

Then I measured the voltage coming from the O2, and it was very faint, never went over .25V, so I got a new O2 sensor and now everything is back to normal, I adjusted it, lambda fluctuates beautifully and engine purrs like a kitten. Not bad for a 19 year old car.

I'm just suprised that this O2 went bad after such a short time. I had it in the car less then a year.

If anyone is interested, it was a Neihoff O2 sensor for the Ford mustang. This time I got the Bosch one and the car seemes to like it a lot more.
