Guys I've noticed over the past few weeks that when I start my car after driving it a few minutes prior (drive to grocery store, get groceries, get back in car and drive home) that the motor will run a little lean (between 15-16 afr ratio), and after a minute of driving everything will return to normal (between 13-14afr while idling and driving without boost). Anybody else experience this issue. Just seems a little odd. The motor doesn't sound funny while doing this, but it's just a question that I've had stuck in the back of my head for some time now.

yeah I generally get a 12-13 on a cold, and idle usually 14-15... however I do sometimes while idling the car will slowly drop to a low 16-18 range... which is a little annoying. but doesnt do it often and a little tap on the gas fixes it.
