as soon as it stops running like it used to...

Need to replace the actuator.

It sounds like a loose wire at the MAP (mass air flow) the MAP is telling your car to throw a large amount of fuel in the chamber, if this is not the case then its your flexplate (flywheel)

Try unplugging the blower motor, heater control unit and blower motor resistor. Replace the fuse then reconnect the items 1 by 1 and see what pops the fuse.

Sounds like you might have an ignition coil pack going bad.

sounds like you are having trouble with fuel pressure

If all you get is a brief turn of the engine, chances are it will start if you jump start the battery. Once running, take it to a parts store and ask them to test the charging system. If the battery is much over 4 years old, you have to question it's veracity.

might be valve stem seals or rings

Sounds like your TPS is bad. Throttle position sensor.

You have probably solved the problem by now, but the first thing to do is re-check the coolant level once the engine cooled off. You may have cracked the radiator or the hose. Then the question becomes "what caused it to run hot".

The light comes on and goes off when you start the engine as a test. If the light comes back on, there is a problem and you need to get the body computer scanned for trouble codes. The traction control uses the engine and ABS braking system to work.

Oh no... I have bad news... you have coolant leaking into your engine oil. STOP DRIVING!!! You WILL seize up your motor. Depending on how badly you have over heated the engine will depend on how damaged your motor is. Could be just a seal like your head gasket (most likely), or you could have a cracked block. Let your vehicle sit and cool down, drain your oil taking a very close look at the first fluid to exit the drain plug. Water is heavier than oil. What I like to do is run it over a piece of cardboard, metal flakes will settle on the cardboard, any big chunks and you have an issue.

Depends on how it blows. Can cause oil to mix in coolant or coolant in oil. Can also let coolant into cylinders to cause steam in exhaust. Or, combustion gas into coolant--this will cause overheating. You can tell this one from other types of overheating by noticing bubbles coiming into the coolant reservoir or up the radiator with the cap off. Let us know if you have more questions.
