2008 Hummer H3 stalling when closing throttle

[Tom B.]

Has anyone had issues with stalling when letting off the throttle. The only DTC is P0102. The MAF is reading zero volts. Wiring is intact and the sensor has been changed.

Whats all done to the truck?

[Tom B.]

Nothing. The truck is stone stock.

Sound like your MAF failed physically or it might be a broken wire... but you do need to diagnose this to make sure.
