When the MAF sensor is disconnected, the computer run the air flow mgt. in a kind of safe mode which might affects the fuel efficiency.
Let's assume you replace with the correct MAF sensor. Check the harness for any damage or shorts. You may also want to check the intake air temperature sensor (IAT). This could also affect the idle and the computer uses its feedback with that of the MAF to control idling among other things

SOURCE: stalls when put into gear

Its possible it could be other things causing the problem, but seeing as you've checked most of the likely causes, it is most likely your Torque-Converter. The lockup clutch in your Stator-Fan located inside the Torque-Converter could be siezed, causing the car to stall.

SOURCE: engine stalls, check engine light, not fuel filter.

the white smoke as it stalls could be steam in the exhaust. This is caused by coolant leaking into cylinders from a leaking head gasket. You should check cylinder compression next with a compression tester.

SOURCE: 2000 kia sephia constant engine stalling!!!

try this procedure and let me know if it cures the problem.

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

97 buick regal gs runs fine until warm then stalls and will start for more than a second. sometimes when i give it gas it will rev for another second then stall


When the engine warms up the engine computer goes into closed loop mode and relies primarily on the O2 sensors and the MAF sensor to calculate the correct fuel to air mixture - if one of the O2 sensors is fouled or the MAF sensor is not working properly, this can cause the problem.
Given the age of the car, I would also check the idle air control (IAC) and channels, the EGR valve and the throttle body for carbon buildup.

How to test maf sensor


you cannot test a maf sensor without an oscilloscope. it has a filament inside which is fed exactly one amp of power and it heats up. as air flows past it it cools down and the speed of this cooling down is relayed to the pcm as a pulse-width signal. if you disconnected it and noticed no change, it is probably good or the computer does not see it at all, but then a code should be set. look for clogged injectors or a weak pump because the computer does not monitor that part of the system, you might see a lean running code or a multiple misfire. clogged injectors do not give enough fuel for a cold engine, it might even misfire, whereas once it warms up it doesn't need so much fuel and it stabilizes. oh, and by the way, whack the maf sensor with a screwdriver handle and see if the motor stumbles; if it does, it's a bad sensor(you don't have to whack it too hard, just enough to jolt it; a rubberized handle works best)

Check Engine Light - Code P0171


brass fitting might go to air cleaner look under it for the hose.
see if the ground wire reaches the engine block. It could be the computer ground for the sensors.

i had the same problem a few months ago. check your fuel filter. mine was on the car for some time and after replaceing it, car runs great. hope this helps. i would also check your air cleaner. if to dirty will run rich and with a dirty fuel filter your car will stall.
