1992 dodge dynasty,fail smog,fuel tank and system not holding pressure.checked all lines
Could just be a bad gas cap, as they are fairly cheap just replace it anyway, clear the code and road test, if the code returns, then it could be a stuck purge control valve in the fuel tank vapor system. Man a 92 and your still having to smog it, out here in the upper portion of my state if it is over 10 years old it goes exempt, the other parts of my state it is not required.
