We have a problem with our LeSabre. When the engine is cold it runs fine for about 10 mins. When the engine warms up it starts to idle up and down (like its got a vacuum leak), but also it tries to die when coming to a stop and sometimes does die (always starts right back up). We have replaced TPS, MAS sensor, IAC sensor, replaced a few vacuum hoses, catalytic converter, alternator, brain, O2 sensor, and serpentine belt. All of this with no luck! Please help!!

Wow! THere isn't much left. Have you checked the EGR to make sure it isn't sticking? Also, make sure there are no intake gasket leaks. Finally, have you replaced the fuel filter reciently or checked fuel pump pressure?

Let me know what you find.
