I went to the dealer cuz my check engine light was on and they said that I needed a new roll-over valve and that it was going to be $300 to fix it.They said I could drive with it like that but that I would get really crappy gas milage. Does anyone know anything about this and where I might be able to get it fixed or if I can do it myself??? That light is pissin me off!!!!!!!!!!

my chilton's manual don'tsay anything at all about a rollover valve.. a valve open and closes by moving back and forth why would it rollover to open and close? i suggestyou go back to the dealer and ask if you needto replace your piston return springs, and your muffler bearingscause they are liable to be yanking your chain... or just ask them what they are talking about they can tell you that much and explain the repair necessary...
