I got a used MAF sensor. No change. But who knows if the used one is any good.
But in the meantime I did a little science project. I disconnected the wires from the MAF sensor. The car runs fine, even when warmed up! No stalling! (I'm getting code 34 of course.)
Who knows if the acceleration is still the same, or the gas mileage, or if the emissions are correct. But no stalling! And state emissions inspection is 16 months away.
I think what is happening is that the computer uses two inputs to decide on how much gas to inject: the throttle position and the MAF reading. When the MAF sensor is disconnected, it just uses the throttle position as a first approximation, which works better than using garbage results from a bad MAF sensor.
Next research question: what is the gas mileage with the MAF sensor disconnected? Stay tuned.
