pcv valve?
i noticed on the autozone bags it says to change your pcv or pvc (i forgot what it said) valve every 6000 miles. what is it and what does it do? does a bad one hurt anything?

from what i can sorta remeber from school. there realy is no way of telling if it is working or not. but when it goes bad your car will start to get poopy gas milage, and you motor will not have as much power. other then that i dont realy think theres anything else.

If they shake, they're probably okay. Try sucking on the vacuum side and and the plunger closes down to reduce air flow during idle. Try with new one. Mine I changed out was the same.
Just made me feel good to change it and transferred some money to Fram.

What are the symptoms of a bad PCV Valve?
My '95 FSM lists these:
A plugged valve may cause: rough idle, stalling or slow idle speed, oil leaks, sludge in engine
A leaking valve would cause: rough idle stalling, high idle speed.
