Engine Stalling Due to Mass Air Flow/Crankshift Position Sensor Failure on Pontiac Bonneville

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

2000 Pontiac Bonneville- 3.8L V6150,000
Stalling while driving, not restarting or will restart but then dies within minutes. Surges forward and RPM needle jumps all over the place. Have spent more than car is worth and replaced every sensor Known to mankind yet problem still persists.
1997 Pontiac Bonneville- 3.8L V6223,000
car surges when n idle or at a stop light acts like it wants to cut off but doesnt already had the ignition replaced no solution for problem
2003 Pontiac Bonneville- 3.8L V6105,000
intermittently stalling and engine RPMs revving up
2000 Pontiac Bonneville- 3.8L V6 Supercharged
Stalls Intermittently, as if the key were taken out of the Ignition. No Consistent Condition leading to stall.
i could be driving down the road then all of a sudden i will lose power and the car will shut off
2004 Pontiac Bonneville- 3.8L V6175,000
engine would start up and run fine till temp reached 200 degrees then it would run rough and stall and would not start back
2002 Pontiac Bonneville- 3.8L V6137,000
Engine stalling intermittly. Change fuel filter and installed new plugs/wires. No change.

Random stalling was resolved by replacing the Mass Air Flow Sensor.
Stalling when you least expect it!! Replaced MAF etc - Crank Shaft Position Sensor is next.
1999 Pontiac Bonneville- 3.8L V6
I've had to replace the MAF twice within 2.5 years, and I'm having the same problem for a third time. 1. The car will occasionally die while driving (between 25-45 mph) 2. It usually starts fine, but there are times when it takes several attempts to start it and keep it running. Worsens over time, and eventually have to replace MAF...again.
1994 Pontiac Bonneville- 3.8L V6 Supercharged
Engine just stalls and replaced sensor and now it revs up on its own.
2001 Pontiac Bonneville- 3.8L V6 Supercharged155,568
Reluctant to start but turns over great, stalls intermittently, idles higher RPM than normal and surges when accelerating. Pulled the MAF sensor connection and everything evened out. Planning to replace very soon......
My car is not running right, it is not picking up speed . i press on the gas and it spudders and it shuts off and act like it don't want to start
2002 Pontiac Bonneville- 3.8L V676,000
Car was fine and then it wouldn't stay running one morning. Disconnected MAF to let car run speed density mode and it ran. replace MAF and no further problems.
2003 Pontiac Bonneville- 3.8L V6137,122
car stalling out and or losing power for few seconds,gotten to the point of shutting back off as soon as i start the car,was told to try using mass air flow sensor cleaner first and see if that fixes the issue
2002 Pontiac Bonneville- 3.8L V6125,000
Random rough starts when cold, normal starts when warm. Momentarily stalls at random engine ram's, never actually dies, just happens super fast, similar to shutting the key off for a couple of milliseconds.
Engine surges and kicks around 3000rpm and wont run past 3000rpm changed the tps because read tps low voltage and now doesnt run past 3000rpm
2002 Pontiac Bonneville- 3.8L V6154,000
Engine stalled intermittently but then could go more than a day without a problem. My mechanic said when he tapped on the mass airflow sensor with the back of a screwdriver, the engine would sputter, so it seemed likely to be the problem. He replaced it, and there have been no stalling problems since then (2 months ago).
2002 Pontiac Bonneville- 3.8L V6 Supercharged189,000
Car sat for roughly a year had the engine rebuilt, oil changed and the mass MAF cleaned out. It ran for a solid hour driving no problems, now when you start it you can see the psi creep up causing the car to stall with in seconds. Tried replacing the supercharge control boost silnoid and it made no difference. help!?
Rpm' s jump around, doesn't idle. Will shut itself off. I'm thinking it's a sensor.
