Technical Rough idle when engine is cold

[AnthonyH]

The engine on my 500X is a bit rough when it first starts with a cold engine. There is some fuel that appears to be coming out of the exhaust for a few minutes and then the problem goes away.

I've changed the glow plugs and disconnected the MAF sensor but it made no difference.

No error codes.

Ideas?

I saw talks about a video with the problem, in the thread that got me here.
Where is the video?
And... you say it's fuel. Is it coming out on the return pipes washers? What are you going to do about it?

It was such a tiny amout of smoke that i deleted it, better to post one that has plumes ! LOL

I meant the exahust fumes smell of fuel, so that there isn't proper combustion for the first few minutes after the engine is turned on.

Fuel pressure desired Vs actual

Fuel leak of test

Crank speed
