Between work, the holidays and a back injury, I have been testing out how long this problem occurs without clearing it out. It takes about 30 sec to 1 1/2 mins then it will clear itself.

I have also have an OBDII bluetooth scanner. After start up, it takes some time to start sending data to my phone. But I finally got some data while issue was happening. First two screenshots are of the O2 sensors when its stumbling at idle. The next two are as the problem clears itself.

O2 2x1 would be Bank 2 and it looks like it may hold some clues. This is all happening under 150 degrees. I think it may explain the rich smell. Which side of the engine is bank 2?
