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.

Its hitting 15-16 on hot starts, and 13-14 on cold starts. The wideband sensor is brand spankin' new. The factory sensor is original. Perhaps a good cleaning is in order??? When i boost my afrs will drop into the 9-10.5 rangr beyond 4000 rpms. What should i clean the sensor with. Or if i need to replace it can i order the sensor from a 94 mr2?
