Re: 1997 Expedition 4x4 5.4 dtc 442
well Bert, it sounded plausible and I was hopeful but a close inspection of both sealing surfaces showed no reason for a leak there. I have the shop manual on CD and I need to read the section on the EVAP system over to remind myself exactly how it works and sets the 442 DTC. Then I'll make a plan find the leak.
Thanks for your reply,
