1999 Buick Lasabre started idling rough yesterday, overheated for about a min and heat started blowing cold air, check coolant; almost empty, refilled. Took several starts and accelerations to get it to start back up. Stalled out on the 2 mile ride back and noticed a white smoke coming out of the tailpipe briefly and a rotten egg smell that lasted only a few mins. Let it sit over night. Now it starts and stalls immediately.

SOURCE: white smoke from exhaust

Hello;
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.
Thanks;

SOURCE: Car died rotton egg smell

Not sure if engine coolant smells like rotten egs when it burns inside the cylinders , but it sounds like you may have blown a head gasket. Coolant and/or oil could be getting inside combustion chamber. Another possibility is that the catyletic converter might have broken up and colapsed onto the screen where it goes into the exhaust. Might give the rotten egg smell and block the exhaust enough to cause backpressure sufficient to cause the engine to run poorly too.
Try putting your palm over the exhaust pipe , if the exhaust is coming out in pulses (pop ,pop,pop) thats normal , if it is just slowly flowing out with no noticable pulses , I would check into the cat converter problem.

SOURCE: car is hard to start, keeps stalling, white smoke coming out of tail pipe

It sounds to me like you have a head gasket leaking. See if you can get a gauge and check each cylinder. Are you using alot of anti freeze?

SOURCE: 88 pontiac 6000 shudders and stalls after approx. 30 min. driving

What was replaced in the tune up? Usually the coil paks cause these types of issues. Also fuel filter or fuel pump will allow enough fuel to start and sputter like you describe.

2002 Buick Rendezvous no heat and over heated after warming it up for over 30 minutes.

Have a pressure test done on your cooling system, you sound like you could have a leak in your system or your system just needs to have the air bled from it. Check your coolant level also, with air in the system and not enough coolant it will blow cold and cause overheating.
