The in-laws 2004 Chrysler Town & Country minivan has developed a problem in the last couple months where following a fuel fill up the van will stumble and bog down for a couple minutes after leaving the gas station. A quick bit of googling was enough for me to learn that it not an uncommon problem. Most things I found either just report the problem or say that the entire gas tank needs replacing. Some say this is due to a faulty rollover valve, some say it is an issue with the evaporation system sucking liquid fuel instead of fumes. Some people get stalls others just get rough running and lack of power and some people report that the engine stalls and the steering and braking systems become inoperable. That one I understand, but what it the root cause here and how can it be fixed?
The dealer reprogrammed the transmission computer to 'fix' this a couple months ago. That improved the shifting, but not the real problem. I think they may have also replaced some sort of solenoid or valve in the evap system. Not sure exactly what they did, but it didn't fix the issue. They are in town for Christmas and I figured if I could get the answer to their problem it would be here.
Thanks, T.J.
