When your car does not run properly you need to assess why. You should take your car to a mechanic if you're having problems with it.
It will run poorly, waste gasoline and pollute the air.
it don't start or run or move.
It won't run properly, you'll have to drain the oil all out.
no
you'll passs out lol
only if it has a diesel engine. A gasoline engine will not run properly on diesel fuel.
It will always run cold so it will run inefficiently.
Not if the cooling system is operating properly.
If the switch is properly bypassed, then yes.
The transmission will shift to the appropriate gear, if it's functioning properly. Otherwise, you'll either run really high RPMs, or you'll bog down.
Some cars can run without the airflow meter (though not properly), others cannot run at all.
If you do not properly wear your seatbelt you will die if you get in a car wreck.
if you are referring to the evaporation system in a car, you will get check engine lights and/or the vehicle will not run properly.
