Rene - your canister may be hooked up wrong, the three hoses not connected properly. And it should actually be sitting upright inside the right rear fender. If you have the BBB (Big Blue Book - factory manual) there is a good description of the set-up in there. If the canister is lying inside the trunk rather than being positioned correctly, this may cause your problem (which is probably a safety hazard as well! - do you carry a fire extinguisher in your car?).
