I researched what might cause that injector spike and pulled the injectors and changed the screens plus I checked the connection at the knock sensor, which was questionable, so I changed the connector. Every time I load a bin to the ostrich, I first disconnect batt neg wait a couple minutes, load bin then reconnect batt. So, I loaded the 2022 update bin and It worked great for the first drive but started hesitating between 1500 and 2000 rpms on the second and got worse on every drive. I hit the emulator button and changed linear egr to not set and no change. set- backpressure egr and the idle got a lot more steady. set- 32 egr and the idle smoothed out. I've been on several drives and its not digressing and it's running well. Now that I know this is happening, I will reset the pcm and load the bin before I record a log. might get good data before the wb02 perimeters start making it run bad. I'll post a log this evening for you to look at. Thanks dave w. Add it to the bill
