Hi,

I've been having an unsual problem with my Endeavor. I have the Evaporative Emission Control System Leak Detected (no purge flow or large leak) code registered but we could not find any problems. The thing is when I gas, the truck won't start, it stalls everytime, but it will start fine after that, only when putting in gas.

I have tried with a friend mechanic to get to the bottom of it to no avail. This week, we changed the fuel vapor pressure sensor but that was not the problem. Until we do find it, we have disconnected the sensor as this solves the gas problem (let me tell you, it's very annoying having it stall everytime you gas). Does anyone have an idea???

Thanks
