    Mine keeps setting off P0442. The only thing the Tech-2 can do at this point is reset the code. I've run the tests but it has passed them all. Need to get a smoke machine and a decent one is $200 clams. I do have some 7.2V smoke generators from my rc tank days but not sure it would pump enough smoke to fill the system.

    if it is the gas cap make sure you go with oe and not aftermarket.

    James I would gamble on the small evap leak and replace the front solenoid they are like $25-30.00 that's what it was on mine, watched some videos and they can can get "sticky" it might work one time and then not the next or if it was a little to cold that morning, etc.. in one a guy was taping on it with a hammer and making it work and not work again.

    Well, it passed the tests with the Tech-2 though, no leaks. I'm thinking it's a line or connection somewhere else, probably under the truck on top of the gas tank, the most difficult place to access!

    ya this guy was saying they can be intermittent it might pass one time and then not another time, so I was just tossing it out there as a possible cause
