This was posted on another site. I wanted to get this out there so that the awareness level is started. Look out for DTC P1450.
"Whenever you put gas in it, the car starts and them immediately stalls. It takes multiple attempts to start it. Once it starts, it runs fine and starts and stops fine. It throws code P1450, which indicates excessive vacuum in the evaporative system. Now in most vehicles, including older escapes, this isn't a big deal. Its actually a common issue, and is a known issue for Fords. Usually this is caused by a bad purge solenoid, or simply a clogged/dirty evap canister or hoses. You can literally replace the entire system in this car for a couple hundred dollars in parts. On the escape there is actually a replaceable pre-filter for the canister, and you can usually take these things apart and clean them out. The problem is that Ford in its infinite wisdom decided to locate the evap box, filter, and vent solenoid in a place under the car that can only be reached by removing the entire rear subframe. This involves disconnecting and removing the rear brakes, suspension, drivetrain, and any wiring from the rear of the car. In the past evap canisters were often located under the hood and when they were located under the vehicle, they were accessible. This was a simple job I was hoping to do myself, but unfortunately, it cannot be done without a lift and an extended transmission jack, plus hours of teardown, brake work, etc."
I have looked under the rear end and sure enough, its buried way deep in there. I stuck my iphone up in there last night to get a picture. For those of you with workshop manuals or experience please chime in. I'm still looking for a purge valve in the engine bay. The workshop manual is very vague and Tasca parts or motorcraft doesnt even list one, so I'm wondering if this new "system" even has a traditional purge valve to check your vacuum. Someone told me that even if there is one in the engine bay, you have to take off the intake to get to it. That kinda makes it hard to check your vacuum. Thanks Ford.
Sorry for the long thread.
