I GOSE BB BBBBBB BBBBB boo
it goes "BOOM" :)
your engine is wrecked
There will be no water pumped into your engine to cool it, then you might need a new engine.
When your clutch goes out your rpms will climb up, but you will get no power. essentially your engine is in neutral, and therefore not transferring any power from your engine to your transmission.
you have a big problem
The engine will not run.
It burns up and goes to the engine to power it so your car can move
When the oxygen sensor goes bad, the check engine light goes on.
Engine will overheat. Possibly seizing the pistons and totally wrecking the engine.
MP goes down
The engine won't start.
It goes into reverse gear, nothing else.
