Friend of mine had the same code on his 2K. Tried replacing the gas cap first, didn't work and ended up bringing it to a local shop that injected smoke into the system to find it. Can't remember exactly what it was but they fixed it with epoxy. Look it up at gearchatter.com, might find an idea there.
