ya those are dead. Lets see if new o2 sensors fix it.

 

In sdd try and narrow down the range on the live data to get better resolution. For instance if the plot shows a straight line at 15 mA set your limits on that line to be minimum 14 maximum 18 and then look at the graph and then you’ll be able to see if there’s any up-and-down movements

 

Also in SDD for the first sensor you want to look at the current and on the second sensor you wanna look at the voltage. So when you set up the live monitoring pick oxygen sensor bank one sensor one and bank two sensor one look at the current and for bank one sensor two and bank two sensor two, look at voltage’s

 

It won't let me upload it here, but that is a screenshot of a video in which the car idles then revs up to 2500RPM and then falls back to idle.

When it falls back to idle the current on the upstream sensors goes up to 9.7A. That's right, 9.7 Amps, not milliamps. See below:

P.S I've also ordered a replacement MAF sensor. Might as well do everything.

 

Having absolutely the same story, did you find out the problem ?
