Question about 2000 Buick LeSabre
This car has been doing this for months. all of a sudden it will load up, miss, and sometimes stall out. It will start up again and i clear it out and its good to go again for sometimes a couple miles and other times a few days. Of corse i cant duplicate the problem to check anything. No codes present either.

U DON'T HAVE A CARBURETOR SO FORGET THAT, THE FUEL REGULATOR WOULD NOT CAUSE THIS PROBLEM. I AM A GM FACTORY TECH AND KNOW THIS WITH CERTAINTY. U COULD HAVE SLUDGE IN THE IDLE SPEED CONTROL AIRBYPASS VALVE.

i had the same problem with my 92 exept after mine stalled it wouldnt start for 20 - 30 mins... mine ended up needing a transmission flush for the stalling problem and i tried to drive everyday that helped
hope this helps in some way

SOURCE: 96 Buick Century stalls....
I spent endless time on this same problem on my 1992 Wagon. I changed out the computer but no help. It turned out to be the top dead center crank sensor that tells the system when the crank passes TDC. It is a small magnet essentially about the siz of a pencil eraser in the flywheel. it was cracked and occasionally would not "sense" and the car would just quit. troubleshooting was a nightmare because the computer diagnostics on the 1992 are less capable than the 1996 model. Anyway that is a relatively inexpensive fix and easy to know if it worked. Let me know how you solve this.

I'm not Roger but can tell you this....if you have a bad crankshaft position sensor or a corrupt ECM....your car will do that.....last things could be the timing belt.
