The 2nd Log posted did not have the engine running.
The fuel system status is in error and they Pre-cat O2 sensors are not looking happy.
Get a 4 minute warm idle Log and also check the fuses inside the DME box as well.
Something is not right and I do not have enough data to blame any one thing.

It's great when we understand in depth information but the key is translating those details into the level of knowledge of the audience. I think that is troubleshooting steps that anyone can do since we can't quantify the capabilities of anyone.
I would have started with troubleshooting to eliminate the MAF (as upallnight suggested) as the cause since OP had just cleaned it--probably not a coincidence problem started after cleaning the MAF. As an example, what did you use to clean the MAF? Did you spray the rather hidden wires? Are you sure the connection is seated? Is there a break in the wires to the connection? Did you unplug the MAF to see if there is a change in the idle. Is acceleration normal?
The basics that most anyone can do--how to eliminate causes such as-- air restriction, bad MAF, vacuum leak, low fuel pressure, no spark, etc.
