One last question.

I can't bring the car in until tomorrow so I have one more day to think about this.

If the stalling problem turns out to be the potentiometer, could this fluctuation of voltage actually damage the ECU/KE Controller? I ask because the ECU replacement did make the problem go away for awhile and when it acted up again my first thought was that there is another problem that is damaging the ECU. So if I simply clean the potentiometer or replace the entire air-flow meter will I still experience problems because the ECU is damaged and I will need to acquire another used ECU?

Probably thinking too much...

Thanks.
