It'* a toggle.. something that you need to experience to see.. I would say a good reading is probably flipping from one number to the next about twice a second. It is hard to describe.

Exactly. It'* more of a 'feel' thing. You almost need to know how it acted new, so you can compare to what it acts like as it gets tired. It'* not really a defined diagnostic, but more of an indication. There is no toggle rate definition that could say good or bad, but it can give you an idea.

Drifter,
I'll try and scan my car at idle tonight and I'll send you the logs.... I'm not sure if Bill has a scanner/tuner or not, but if so that would be three 97 SSEi'* logs to look at and compare.
But honestly I think if you just watch for a "flip/flop" between two values, that'* all you really need. Just as long as it isn't "locked" in at one value.

Thanx for the offer guys.
Merlin. Will you be doing it with a car up to normal temp?? Or cold?? Or just up to temp from idling ( where the oil hasn't reached operating temp )
So when I compare I can reduce some of the variables. ( Or get them as close as possible )

OK.. I don't know how to get a continous log on the 02 sensors yet.. but I ran the test on the 02 from the scan tool and this is what it says
rich to lean switch time are .04 Sec PASSED
Lean to rich switch time are .03 Sec PASSED
I"m unsure bout the graph. I will attempt more later on tonight when I can sit in the car and try again to find which settings it is to use for the 02 sensor with the scan tool.
I did notice however during the run onto the highway from work parking lot ( while car hasn't reached operating temp ) that there was no KR.. so now I"m wondering if Mustafa Drunken Monkey has nailed it with a tired 02 sensor attempting to lean the car thinkin it'* a rich setting when up to operating temp since during warm ups the car runs in a richer setting correct??
I guess I may have to break down and buy a new 02 sensor
