I think you may be onto something with this. I watched this on my scan tool this morning. The air temp and IAC was a bit warmer this morning, starting at 46 degrees, so the car went into closed loop almost right away. I didn't notice the stumbling nearly as bad as prior and it completely cleared up very soon, before the engine temp even hit 100 degrees.
I'll try it this weekend or next week as we are supposed to have cold temperatures again to see if I can drive it more while still in open loop to confirm the correlation. I'll report back with the results.
