Very very difficult to diagnose problems over the internet.
Another issue in diagnosing is that the Durametric expresses data over units of time (bottom axis on the graphs) as compared to frames when you watch something like ScannerDanner's video's. Makes comparing data a little more difficult.
You may want to look at ScannerDanners vids on Catalytic converter efficiency or his vids related to the P0420 or P0430 codes. In most of his vids there are examples of bad and good wave forms on the graphs. May give you better insight then I am giving you 
I know you don't have the P0420 or P0430 code but your post Cat Sensor signals still seem a little suspect.
Hope I am not leading you down a wrong path. |
I definitely agree that the fidelity of the data from the durametric is troubling at times. The fact that the length of the time steps are inconsistent really gets to me. I will take in some more of ScannerDanner's videos and see if causes any ah-hah! moments. As soon as I can get those O2 sensors off and check the back pressure, that'll be a big data point on whether I need to focus on the exhaust to solve this issue or not.
Thanks again for following and helping!
