If it's an automatic transmission I'd suspect it may not be shifting out of overdrive and this is causing the shaking and stalling. There is a plug on the transmission that can be unplugged and vehicle can be driven without any damage. I've been told it's a common problem with these cars. Ask your local mechanic about it.

Could be a faulty engine coolant sensor but there are other things it could be as well. Might be fuel pump and or relay, fuel filter, vacuum leak, gas cap, might be ignition components(p/u coil, coil, plugs, wires). Take a look at the cars maintenance history and if the engine light comes on while this problem occurs, have it read. It might help you or put you in the right direction.

I have a 1994 Toyota Collora that shakes and vibrates when applying the brakes to come to a stop and when in idling. More so in the park than in the drive position. Car is a automatic, fuel injected.

They all do it, I believe it is in the torque converter. I own two and they both have well over 250,000 and I put some transmisson slip fix in one and it stopped it for awhile...however I wouldn't recommend any additives unless the trannny is really slipping.

I have a 2004 pontiac grand am and when I drive over 70 MPH and allow my car to slow down on its own the front shakes and makes thudding noises what do I check for and how can I fix this?

This sounds like a worn out cv joint. You should have a qualified mechanic check it out. It is impossible to say for sure what it is without checking it.

My car dies when it get warm?

sounds like a your tie rod ends or ball joints are bad. as far as it turning off in gear means that the fuel injection is screwed up which means its a gas problem which is a intake problem with wrong fuel mixture or even a vacuum leak.
