My 2002 Buick LeSabre idle fluctuates and dies when coming to a stop. I have changed the air/idle control valve, the MAP sensor and the MAF sensor was changed recently also but the problem still exists. What should I do next?

Test the fuel pressure while idling and while driving. If the regulator goes bad it will cause high pressure in the system and the symptoms will disappear at higher rpms.
