Welcome to AF.
Which year, model Grand Prix and engine? Link below has helpful info but the P0442 DTC may require proper test equipment to find the small leak.

That can be a hard one to find, even with all the know-how and diagnostic tools. All you can really do without diagnostic equipment is look for cracking hoses and check the ring on the gas cap, if it's cracked at all it can cause a leak.
