[my9250GT]

ok here it is i have a 92 gt 5.0l with a mac cold air induction kit i am running bosch platnum 4x4 plugs and motorsport 8mm wires.
i am getting a strong gas smell from the front of the car where the air filter in the fender is i have checked all the plugs, hoses, wires and caps that look like they could come loose and everthing is tight and snug. someone advised me to check throttle body and pcv valves well the throttle body looks to be tight the gasket is in good shape and the pcv valve is tight at least what i think is the valve looks good. where is exactly is the valve and what does it look like? i have looked for loose connections behind the motor next to the firewall and all is o.k did i mention i can smell it while i come to a stop at a red light...yes its that bad. by the way all the connections by the charcole box are ok. so if anyone can help me i would appreciate it ALOT!!!!
