Buick has periodic starting and stalling problem

I think there is a Technical Service Bulletin on this>>>>>>http://www.automd.com/tsb/buick_m/lesabre_mm/1992_y/

reviewing that link am finding nothing of this problem listed...am going to have to say get a new battery and clean the black battery cable, the end that goes to the chassis ground with a coarse wirebrush. This is overlooked because everytime you start the engine the dissimilar metals "weld" themselves leaving a layer of corrosion creating an "iffy" supply to the computer....shame they share the same grounds 300 cca starting amperage and perhaps 750 mA together for the last time....maybe they will see the error of their ways....~

I had the same problem with my sons 89 Buick lesabre after changing multiple items that never fixed the problem I finally replaced the ecm and prom chip from another car at the local junk yard and it fixed the problem before I did that I replaced fuel injectors fuel regulator cam sensor crankshaft sensor fuel pump spark plugs and plug wires battery coil and icm ignition switch key lock cylinder tps sensor changed every vacum hoses temp sensor Egr valve iac sensor maf sensor so he has a car that now runs great and I don't regret changing any of those parts they all need to be changed I am sure the previous owner didn't do anything except oil hope this may help someone
