Hey, I have a similar problem with my 2002 Ram Quad Cab 4x4 except I get the P0455 code which says evap fuel system gross leak detected and it switches between small leak and gross leak, and I am still trying to get the evap system diagram so I know where to look for possible leaks, as a precaution I replaced the fuel cap which was new less than a year or so ago... but it wasnt very good.. so I bought a new one and cleared the trouble codes with my scanner and it was a couple days before the code came up again... anyway if you figure it out can youo let me know what you did and where to look for a likely problem?
Thanks
Bill
