1999 V70 XC (turbo) put in the new PCV system from FCP Gruton. Last night I finished it all up, started it up and it is barely running. I am going to trouble shoot tonight or Monday. I thought I would ask and see if any of you have ran int0 this before. Going to check the code from the CEL and go from there.

 

Sounds like vacuum leak. And it doesn't have to a large hose disconnected. I repaired a small hose and it made a big difference.

 

thats wat i am figureing the prob is.
