    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.

    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.

    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.

    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.

    My car has the same problem u describe so i went and got a fuel pump but in the box the fuel screen was not the same as the one i removed so i ended up putting in the old fuel screen but a new fuel pump motor it runs better but still stalls when i come to a stop 10 months prior I changed the crankshift position sensor i also discovered when i punch the throttle all the way down my excelhiration goes up and down could that be the mass airflow????
