Buick LeSabre Problem Report
Buick LeSabre Engine Stalling Due to Mass Air Flow/Crankshaft Position Sensor Failure
Stall occassionally...On Highway, on side streets sometimes within the first few minutes of running and other times you could have been riding for hours and suddenly it uts out. - Visitor
car kept stalling, so i removed mass air flow sensor and cleaned it with maf sensor spray, i also replaced the idle air control valve after first checking for vacuum leaks. total cost iac valve $20 maf spray $5. sorry i forgot to update, the problem came back so i went online and brought a new maf sensor from advanceautoparts.com for $100(using coupon code to save $25+) installed (takes 2 minutes) car has been great ever since. 16,000 miles later no problems with stalling. again buy the part yourself and install, if you can work a screwdriver you can do this, so easy. - bungle
Once or twice a day with no rhyme or reason car will stall. It stalls at slow speeds and highway speeds. sometimes I can put it in nuetral as I'm still rolling and start the engine again but usually I will have to pull over and wait about 15 min. before car will start again. - RNgirl
My LeSabre would stall out while driving. Sometimes it would start back up right away, and other times it would take 5 or 10 minutes of attempts. No warning lights ever came on, and the computer was not generating an identification code for the problem. Research pointed towards the crankcase sensor being a common problem, so I spent $200 to have it replaced. Hasn't died again since. - Visitor
The engine just shut down today , its like its not firing - Visitor
engine stalling, trans not shifting correctly,poor acceleration. had mass aiflow and map sensor replaced. - Visitor
Not fixed, currently being diagnosed. Intermitten stalling at slow speeds. - Visitor
when engine is run after sitting all night,after driving it for about 1 mile, the engine will make a popping noise like a misfire. I happens every day. thank you - [deleted]
Does not show up on obd diagnostic. I was stranded too many times to count. The crankshaft position sensor is a$35 part and takes a shop under an hour to replace. Just do it before you end up repairing other things that aren't the real prob - Mammashelley
intermittent stalling...was mass overflow air sensor - Visitor
Check engine lite indicated sensor was not working correctly. Replaced sensor - Visitor
stalls at high speeds tach "0"s out very brief hesitation & continues on by itself:: at lower speeds under 50 mph engine cuts off, but can put into neutral & restarts - tomgun
stalls and cuts off. have replaced fuel pump and sending unit, mass air meter and crank sensor. still have check engine light for mass air meter. - Visitor
I have a Burick LaSable 2001 and every time it is damp or wet outside and you drive it the check engine light may come on and starts shaking and try to hessiate when driving - Visitor
first died coming off freeway (fix brake diaphragm in booster)then motor would race was Mass air, then the heater motor would run with off that was the that was the heater control thing in heater box, now my wife just called, what now - Visitor
engine stall while driving - Visitor
Engine would stall at an idle. It seemed to happen every time just as the system went into closed loop as the temp gauge reached the 1/4 mark. - cobbleup
car ran like shit i thought i bought a dud, but it was deeper than the maf sensor itself, the housing where the maf sensor was needed to be replaced also, i guess a rock or something must got through somewhere and damaged the housing it was a few cracks but long story short 150 bucks later car is running like a champ as of 02/04/2015 - Visitor
Highway driving is fine. Slowing down making left or right turns car cuts off. Check Engine pops on and off intermittently also. Took it to Firestone they said the key was bad and needed to be rekeyed due to computer not recognizing key at times. Re-keyed and before I could get out the lot, it cut off. LOL - Visitor
will be driving and car locks up and gas petal goes to the floor and car cuts off. once t crank it ,it starts again and we never know when it will do it again, we changed the fuel filter - netti

What tools are needed to replace it? What is the diagnostic code?
