I have a 2013 Ford Edge with the V6 3.5L with 111k miles on it. It runs perfectly with no serious problems at least. Transmission shifts smoothly and the engine idles perfectly with no ticking or knocking noises. It's quiet and so far haven't had problems with it however.. Yesterday when I started it, usually I let it warm up but I was in a hurry so I left while it was cold. When I started to accelerate quickly it started to hesitate very bad like it was braking by itself. It kept hesitating while it was cold and eventually a few minutes later the engine light started flashing for about 30 seconds. Once it warmed up it ran perfectly fine, I could floor it and it was strong like usual.
Since then I got worried why it did that while it was cold, because when it's warmed up it never acts that way. Someone told me it could be the throttle body sensor or something that isn't right when it's cold. I was confused because the engine is still strong and fine, so I'm hoping it is something simple as a sensor.
Does anyone have an idea what it could be? I would appreciate the help.
(By the way, after the engine light flashing for 30 seconds, the engine light has been off ever since, and I just let the car warm up today to avoid that again)
It could be the spark plugs, have they ever been changed out?
@mrrangerzr1
Actually it hasn't, not to my knowledge. I bought the car last year and as far as I'm aware, I doubt they have been changed. Which is odd because I have a Mazda 3 that I changed the plugs for the first time when it had 180k
A one-time event like that could be hard to diagnose, but whatever caused the flashing check engine light is probably stored as a code in your engine control unit, and could be checked by a GOOD OBD scanner. Me, I'd lay odds it was a loose/corroded electrical connector, because it came and went so quickly.
@glen_stet
I'll try hooking it up with a scan tool and see what it shows me. I'll replace the plugs in case as well. Thanks guys
I had something similar on occasion with my 2000 Taurus with the DOHC Duratec engine. Never actually pinned it down, but it went away when I had to change one of the coil on plugs. It might have been a vacuum leak I discovered when I was replacing the COP, but my money was on the COP. Coils sometimes fail only when hot, or only when cold.
Get someone to check the pending codes. A misfire that doesn't get too bad will flash the CE light, and then go out if it resolves.
