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.
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.
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.

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.

The engine just shut down today , its like its not firing
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
