Why is there oil in my renault intake/inlet manifold

Hi Guyz my name is Steven I own a Renault Megane 2005 2.0L 16v Coupe Cabriolet these are the problems I have.

<1st> the car revs itself from 2000 to 3500 RPM at IDLE and even when I driving it Revs its self

<2nd> the car has the "Check Injection" message on Dashboard, when the engine is it has a rough Idling sounds like its firing on 3 pistons. when I sent it to the diagnostics yesterday it said nothing about the injector rail, coil or plugs which I suspected then I assumed that it was an air leak some under the manifold cause I also noticed that the throttle body doesn't close completely. so I removed the intake manifold and I found that it had oil in it which was strange cause from my knowledge only air moves there.

Now I don't know what to do, please advise

Regards

Nas
