this might be a newbie question but. i was messing around in my car doing donuts and stuff. then all of a sudden my brakes stop working and my car started to have idleing problems. my brakes feel very very stiff but it doesnt brake at all. does anyone know what happen. i left my car off for around 6 hours and its still in the same status. also when im at like around 1-2000 rpm the car shakes and when i turn on and off the car the car shakes. some times the car revs really high when i turn on the car it goes to 2000rpm. and when i leave it with the engine on. the idle drops to 900 rpm and it sounds like its struggling to stay alive. my normal idle use to be 1000rpm so 900 is different by the way.
