Instead of removing your throttle body to look for disconnected vacuum hoses and possibly causing more issues.
Just do a simple vacuum test.
It will tell you if you have a vacuum leak or not.

Ok here are some updates:

I removed the oil cap and the car sounded like its running rough (struggling shaking etc) BUT the RPMs stayed at the same level. What does this mean ?

The car was not fully warmed up tho - not sure if it matters.
