2014 ecoboost, acting like it will shut down

Recommended Posts

l bought this car from a used car dealer last year. Within the first 3-4 months "check engine" light came on. By the time we made an appointment with Lincoln, the light disappeared. We cancelled.

It came on again, stayed on about a week and off gain. We finally took it in after it stayed on for a while and they fixed it.

 

A week ago while I was pulling out of a restaurant parking spot, before i even leave the parking lot it started acting like it s about to shut down. I put in neutral, and try to press the gas. It had no effect.

I finally shut it off and started it back up. check engine light came on, and then off the next day.

 

no problems. drove it for 2 days without an issue. 

 

Yesterday it did it again while I was waiting to pick up the kids from school. No check engine light this time. This time it shut off.

 

Today i have been driving it more than usual trying to see if it happens again. Nothing. drives like new.

The dealer said that the check engine light must be on to troubleshoot it.

 

Any thoughts?

Are you aware that the engine will shut down automatically if you have been idling too long?

 

If you have the owner's manual you can find this under "Starting a Gasoline Engine | Automatic Engine Shutdown" in the Index. If you do not have the manual, you can download it from the Lincoln website)

In addition to this, you didn't give us the code that was found when the dealer fixed it. What was fixed? What does the service ticket from the dealer say?

 

I'm not quite sure what the dealer is trying tell you but even if the light is not on, the car's ECU should retain the code in it's memory for 5 key cycles. If the CEL comes on again, go straight to the dealer. Don't wait. Also, some auto parts stores, such as AutoZone will read codes for free.

It's a sensor. Mine did the same thing last week. Changed the sensor and it's good again. Fuel Rail sensor I believe it was. Code I pulled was P0087
