04 XC90 2.5T CODE P0442 Small leak

[neworleans]

Hello everyone,

My check engine light came on, the car was running little rough when come to traffic lights, I was planning to clean the throttle body because I had no check engine light on at that time but it came on a couple of days ago, scanned it and got the P0442 small leak code, looked over the engine bay, checked the hoses but didn't see anything. Did anybody had a similar problem? Can you guys guide me to look at certain points? If anybody has the vacuum line guideline that would be helpful too.

Thanks in advance.
