Hello i need help ASAP. I have a 2005 Volvo XC90 T6 and the other day while driving i lost power and a message came up that said reduced engine performance. I could not go over 5 MPH and when i got it home i tried to start it and it started but bogged out and died. We ran the diagnostics and it said P2188 (system too rich). Can anyone help me with this problem???
