1994 MX6 LS V-6 5 speed. I am getting a strong gas smell in the garage after parking the car. Also when I am driving and come to a stop I can smell gas fumes if the windows are down. Looked and no signs of gas leak, had car on lift and checked all fuel lines and no leak or wet spots on the fuel lines. Odor seems to be coming from the engine area. Car runs great. Any ideas?
