My car started stalling after every gas up, found it to be this part Ford oem emission system-hose assembly dg9z9d289d* I have tried to get this part but I am told it is on back order from Ford and they won't start sending these out until March of 2018 - this issue causes pressure in my gas tank so much that the pressure makes a loud noise coming from the tank and if you press open the cap less gas input it releases pressure loudly - secondly when this happens the car will not idle and stalls out when you let off the gas - on the highway and everywhere when you let of the gas!!!and won't re-start until after 4 or more tries. This is dangerous!!!! is my gas tank going to explode!!! or will I die after someone hits me when it stalls out? the consumer stated that she replaced evaporative purge valve and it corrected.
