Answer 1

P1451 MERCURY - EVAP Control System Canister Vent Solenoid Circuit Malfunction

You could have a loose gas cap. Start by inspecting the gas cap, if the cap is not damage, firmly secure the cap and clear the code. You can clear the code by disconnecting the car battery for about 30 minutes.
