My friend has a 96 cavalier. he is having stalling / sputtering issues. he took it to a mechanic. they told him he was missing a "charcoal Box". has anyone else heard of this I searched google several times and couldn't find anything. Also if that's not anything then what could it be.

i have no idea what they mean by charcoal box, but if they are being serious, they are throwin you guys for a loop...when was the last time plugs and wires were changed?

its a charcole canister..the only thing i can think of is what my truck has.....but my truck is a 79 toyo pick up so ...try looking up somthing under my trucks listings to get an idea of what it is ...i dont want to explain what it is cuz im not to sure i heard someone explain it to me but i wasnt listening and i dont want to post a false statement about what it is!
