LTFT & STFT die while crusing on the way every time i drive the car..take a look at frame 776 when it starts to happen the car reaches 16 to 17 A/F then after few mins it comes back again and drives great..here is a scan and ignore the Wideband reading because it wasn't hooked up
what could cause the LTFT AND STFT to be turned off while driving?
as you can see when the car enters open loop the commanded goes to .92

Check in the DTC section. If you don't have cats turn off cat montitor.

Make sure you have the latest 2.2.2 installed.
Then, in the engine diagnostics section, disable the cat test and the post 02 test. The Post 02 test diable is new in 2.2.2 and will solve your issue

Can anybody share exactly which DTCs these are? I'm too impatient to scan the DTC list.
