My 2001 Buick Le Sabre Custom has had a few odd problems, it stalls, but only on occasion, and I've it has some big issues when trying to start.
I had a mechanic replace the battery, and the ignition switch. But none of that seems to have made a difference.
I had done a little research online about common problems with the 2001 Buick Le Sabre, and I came across two things that I think may pertain to my issue.
It may be the crankshaft sensor, or the #19 fuse.
Before I go too deeply into more research, I was just wondering if you've heard of any problems with those and if you could explain what they are.

Crankshaft sensors can go bad and not set a code. You have to check to seehow many ohms they have and if they are high they may act up when warm or hot. I have fond no TSB's o nhe#19 fuse which runsthe pcm. But it did say not to use fuses from Harbor FReight but ot use reputablefuses as the Harbor freightones will not "blow". For our problem with occasional stalling, try spraying choke cleaner on the throttle plate on both sides as it tends to gum up and cause your problem. Also spray in the oblong hole as that's it si the idlea air control and it can get gummed up as well. Your car will be hard to start probably after doing this but shold beok. Just be sure to put the air duct on before you start it.
