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.
engine would start up and run fine till temp reached 200 degrees then it would run rough and stall and would not start back
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
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.
Engine stalling intermittly. Change fuel filter and installed new plugs/wires. No change.
Stalls Intermittently, as if the key were taken out of the Ignition. No Consistent Condition leading to stall.
The car drives approximately two-three miles before shutting off and when trying to restart it won't start completely and back fire's after waiting with the motor off for 20. minutes it will start again and run again for another 2-3 miles and shut off again
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......
surging while idling and then ultimately stalling .. loss of power while driving and ultimately stalling. once it dies, takes a few times of starting before it will pick back up and run. if quick enough, can pump the gas a few times and have it pick up and run without fully killing the motor.
While driving my car I find that it will begin to lunge forward as if it wants to stall. Once in park the RPM's will jump all around as if the car is trying to go on it's own. Eventually it stalls and dies. Even with starting it up again, I can drive for only a moment or two and then it dies again.
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.
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
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!?
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 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).
