Hi guys,

I know that there are a lot of threads already regarding cold starting issues and so on. But I really hope that someone has an idea…

I´m from Germany and I drive a 2010 5.4 Raptor. Its hard here in Germany if you have a problem to go to a Ford dealer. They just standing and looking at the truck as it was a thing from another planet. So its a bit tricky here to find someone who's really able to help you with the beast.

My problem is really mysterious and it makes me freakin´out. Mostly when its colder than 5 degrees outside my truck won't start gently when he sits overnight. I turn the key and it cranks and starts with really poor idles. When I´m lucky he keeps running and comes down to normal idle in about 15-20sec.
If I´m unlucky the engine dies right after starting it. If he died I have to give him at least 4-6 tries with the foot on the pedal to get him back alive.

A big chunk of smoke is coming out of the exhaust and it smell of fuel really bad. I´m not an expert but for me it looks like if the engine is basically drowning in the morning. For some reason the injection puts way to much fuel in all 8 pots.

The mysterious thing is - that there is no failure code, no warning lamp - nothing. A friend of mine has an american shop and has a lot of skills with different american cars being a mechanic. But he has no point to start with. Everything seams alright.

We thought maybe the evap system has a failure that the valve does not shut down properly so the fuel vapors not only get soaked in the engine over night but fuel as well. all the sparks are alright, all pressures, all sensor data are alright…no real issue recognizable.

I checked my vin for possible updates or recalls - nothing.

I use different gas stations. I use 95 octane fuel.

I really don't know what to do……hope u guys can help me out.

Here is video where u can see whats going on: http://vimeo.com/84893400

What weight oil are you running? Sounds to me like the oil is getting real thick and not allowing everything to move the way it should. There should be an additive you can put in the oil to help alleviate the problem or you could try going to a lighter weight oil in the winter. Or get a block heater for the truck so you can plug it in and heat everything up

I´m running the 5W20 oil…which is also mentioned in the owners manual as the standard recommended oil for the raptor… the thing is, it does not happen every day. below 5 degrees is 41°F….if the raptor needs a block heater because of this temperatures…then I guess I bought the wrong truck :-D

…and, the truck is doing the same when he stayed in the garage over night…

I remember a few posts here about guys complaining about terrible idle in the mornings. Might check your canister purge valve. In fact there might even be a Ford TSB or something about it, but I don't remember clearly enough.

Search this forum section for "canister purge valve" and a few threads should pop up.

And no, the Raptor shouldn't need a block heater for 5 degrees C! Good luck.

Found the TSB for canister purge valve. Looks like it's only for 6.2L engines though. Sorry.

Thanks a lot guys. This could be a start to replace the CPV.
@pat: The 5W20 is so light - its light like water. In Germany usually all cars running with 5W40 or higher. This is like custard with cold temperatures outside :-D


thanks guys!!!

Possible intake manifold gasket causing a vacuum leak.
thanks hosseface! do you think this issue would place an error code or warning lamp? Or is there maybe some kind of tolerance before the "brain" notice an error….
