heisting when taking off...
MAF sensor failed at 140K miles. Was constantly stalling for about 10 miles then just refused to start up again.
I recently noticed that the air flow sensor or really I think it is is missing from the fuse box I just wanted to know if its mandatory for it to be there so that I can replace it and where we need to go to get it if I can just go to any store I have to go to Charlotte thank you please let me know

Press gas pedal and rpm drops and cuts out and car will die sometimes. As long as you don't press the gas it's OK. Replaced intake gasket, mass air flow, idle air control valve, has good throttle position Senor, cleaned throttle body, checked and regapped spark plugs, replaced all 3 coil packs, ignition control module, had fuel system cleaned at Walmart, tested alternator, replaced battery sometimes, replaced computer with used one and had dealership reprogram
starst and then cuts off cut off at 55mile an hour

Intermitant stalling, would restart after a few minutes.Seemed to be getting progressivly worse with warm weather. Following suggestions in this resource, and position sensor code PO336, changed out sensor. Been driving a week now and no further problems. Thanks to all for their contributions.John R.

04 MC SS died while idling at a stop light and would not re-start. Came out of the blue - didn't have any issues with the vehicle beforehand. Had the vehicle towed and the MAF sensor (battery as well) replaced. Ran fine afterward.
