Shoebox has the F-Body "specific" code list on his website:

P1441 = Evaporative Emissions (EVAP) system flow during non-purge

There is a flow detector switch in the line from the canister in the back fender to the purge solenoid on the passenger side of the intake manifold. In theory, this code indicates the purge solenoid is stuck open and the flow detector is seeing flow when the solenoid is supposed to be closed.

Pull the hoses of the detector valve and off the solenoid. Look for carbon particles in the lines. If you find carbon in the lines, there is a good chance the flow detector or the purge solenoid is plugged with carbon and not working correctly.

Also from Shoebox's Tech Pages (#7 is the solenoid, #11 is the flow switch):
