I am haveing issues with
Evaporative Emission Control System Purge Control Valve Circuit.

Inside of the car smells like gas, when i go to putgas and take of the gas cap their is built pressure and wooshes out air pressure. car also seems to be running a bit rough.

anyone delt with this before, its on my 1996 Jaguar XJ6

 

OK, I figured it out I found a small hose that goes to my manifold and connects to one of those small metal lines in the front, that go to the rear canister behind the rear driver side wheel.
