Just got back from a tech2 run with my lesabre (those are awesome - if you have two and a half grand burning a hole in your pocket, there'* NOTHING like it out there), and I was wondering what'* normal for an oxygen sensor reading.
Mine bounced back and forth the entire time, except at WOT. I'm told that'* normal... is it?
oh, and my readings were between 45 mV and about 900mV at WOT.
I might have some graphs here later, but I can't promise.
Oh, and did you know your IAC actually opens up during acceleration to help you out?? Crazy cool...
And as a last thing, I was keeping track of my IAT'* as well (so I have a baseline for my CAI later on), and the stock airbox keeps the intake air to a few degrees of the outside air... pretty crazy. Never realized it was that close.
Oh, and as the last last thing - I'd heard in the past that turning on your A/C will help the car cool down by commanding the fans on. It commanded my fans on, but at 50 mph and while parked, it actually increased my temps by at least 5 degrees each time. Average operating temp for me was between 190 and 195 degrees. Can't complain about that
