The biggest problem that I have ever seen with that happening has been the wiring for the MAF or the MAF its self.

no it doesn't smoke. a couple of times it has run normal after heating up but not all the time.

check coolant temp sensor.just fixed a car with a similar problem, went thru the wiring and redid it for him and it seems to have gone away.
