I have a 2015 Expedition that has suffered vapor lock a couple of times over the past year. Once was after sitting at a road construction stop for 20 minutes on a 100°+ day. Another time was on a day that was 85° and we had stopped for lunch while on a road trip.
The first time, I had the truck towed thinking the problem was either a throttle housing problem or fuel pump. The tow truck driver, after much quiet thought, suggested it was vapor lock. And, that after allowing the truck to cool down, filling up with gas, and adding a couple of ounces of engine oil to the gas tank might fix the problem. It did.
The second time we let the engine cool, filled with gas and then were able to drive on without problems.
Now, I've been lectured by several mechanics at Ford and independents that it is impossible to have vapor lock on this truck since it has fuel injection.
So, my question is whether anyone else has had vapor lock problems with fuel injected engines?
