Lambda voltage graph
<center><img src="http://img152.imageshack.us/img152/314/logyw0.jpg"></center><p>Hi!
I made log of group 33 values and on a graph it came out that the lambda voltage is jumping all the time during a ride and the aplitude is about 0.7V. Is that normal?
It's 1.8T engine (APY)
Have a look on the graph and tell if everything is allright with this probe. I wonder whether I need to replace it or not.
The specification is that the voltage (green graph) should fluctuate by about 0.3V but here it's more - about 0.6-07V.

well, considering that you didn't post any details about your car...
as the faq mentions <a href="https://forums.audiworld.com/vag/msgs/6768.phtml">here</a>
I'm assuming that you have a front and rear O2 sensor as every OBDII certified car has that's been made since 1996.
