Rough Idle low RPM's
Off to the next problem... 2006 s40 2.4i with little over 132k miles. Had a "system running lean" condition that has been taken care off. (Lower intake manifold gasket was bad) however the car runs rough in idle. No CEL no issues driving just seems to be little rough and the RPM's are around 650-700. I have replaced a few things on the engine so far..
- new PCV oil trap and hoses
- new air intake gaskets
- new MAF sensor
- new MAP senspor
- cleaned the trottle body
- new Vacuum pump
I do have a new fuel rail sensor that I never replaced..

Now I forgot, I was once told tat there should never be positive pressure in the crank case, what about negative pressure? When I remove the dip stick, the engine starts to make a hissing sound.
