Skoda Fabia 2010 1.2 tsi auto pa0068

Hello, I bought this car about half a year ago and I’ve been having my engine light come on and off for the last month aswell as the slip light sometimes , when I scanned with ob2 pa0068 code comes up, and it seems to have a rough idle.  I am going to have a look at the throttle body at the weekend to check for dirt and grime. 
 

My query is about the photo , I bought it and did query the pipe that is  stuffed in the photo bu Didn’t really get an answer and had no issues for 2/3 months. 
the problem seems to go away when I press the pipe in more so it could suggest a loose clip or need changing. The issue is I don’t even know what the pipe is or why the material has been put in there , and my other query is would this be affecting it to trigger my engine light.
