Car stalls while driving?

[Iwant240insteadofP/U]

My friends car stalls if you lightly press on the gas. it doesnt matter if your driving or sitting still if you press the gas without getting on it good the revs drop and the car stalls, its even done it while it was being driven at like 25 mph. when it stalls you can barly even notice though. it seemed sortof strange because most rolling cars that are off that ive been in the engin does a real good job of slowing the car down, but in this car it just rolls forward like it was in neutral. its an auto so do autos go into neutral if they are shut off? the car is a 91 camary its a total piece of crap. his mom was going to tow it so we parked it off in some trails. Some one recently rolled the car down a hill into a bush while we were gone(came back and found the car somwere else). it wasnt to bad probably like a slightly steep 50 yard hill it didnt plow into the bushes to hard but the stalling started after this happend

I know is has nothing to to with Nissan but yall know so much... any ideas? also we noticed his outer CV (cb?) boot is torn, how long would a ducktape fix coting hold up?(this car is almost not worth repair money)

i am not sure if those cars have one, but try changing the PCV valve (like a 5 dollar part at the most)
