Car out of contol ! ! !

It sounds like you have a large vacuum leak and the engine is hittng thr rev limter.I need the exact code numbers you have not the code descriptions.

Are you sure its not a P0711 code?From having to floor the gas to start it I would replace the coolant temp sensor its really common for them to go bad on those cars. Also inspect the connector to the sensor if the terminals are green or blue there corroded and you will have to replace the connector also. The sensor are about 10 let me know how it runs afteryou replace the sensor and inspect the connector. If you follow the upper radiator back to the cylinder head of the engine below where the hose goes on you will see the coolant temp sensor screwed into the head. It has a black wire and a yellow wire going to it.

With the watery sound could be your a/c drain clogged up and that could be water sloshing around. Have you checked to see if that drain is clogged up?That rotational noise in the dash is probably the odometer gear clicking very common on those cars. Its more of just a noise I havent really seen odometer failure because of it I have replaced a lot of the speedometers for noise under warranty some cars more then once.I was told it was caused by the incorrect or lack of lubricant on gears.I wouldnt worry about it too much. Also what is third issue it looks like for some reason it was edited.

The j erking while braking is warped rotors or drums sounds like you live where they salt the roads with the heat shield falling off thats not common at all where they dont salt the roads. So will the idle jump up if your just idling in park when steping on the brake?
