Started having an issue where the ECM seems to reset or something. It occurs randomly and appears to last for 3-4 seconds, maybe less. I'll be driving along and everything is good, then all of a sudden, the ECM goes into open loop and the wideband O2 sensor shows somewhere about .70-.75 on the Lambda scale, then goes back into close loop and all is good.
At the points in the log attached: 07:25:272, and at 12:29:27you can see where the open loop seems to occur for no apparent reason. The strangest thing that sticks out is that the knock counts reset. That is what I find the strangest.
I'm not sure what to think at the moment unless there is something corrupt in the bin file on the eprom that I burned, or, the ECM has an intermittent heat issue.
Any thoughts would be appreciated.
This is a $4E ECM,1228062 TBI 6 cylinder.
