    i was hoping someone might have a more detailed answer to the above code i get on my 2003 360. i know it is a evaporative emission comtrol system leak! as in what part is malfunctioning? it does not effect the car one bit and i drive it normally but the CEL will come on. so any help on what needs to be replaced the next time i have it in would be helpful. so until then i just drive it!

    thx

    P0455 is a gross evaporative leak. If your fuel cap is not crossthreaded and the seal is still intact underneath the fuel cap then the only way to check it is with an evaporative emissions leak detection machine, or "smoke" machine. If you are smelling fuel I recommend a tow to a shop . The most common defect in that system is the roll over valves and seals that are located on top of the fuel tanks. If you own a Spider the capote assembly will have to be removed. Leaking fuel in a mid-engined car = disaster!
