Hey everyone...CEL came on for the first time today...So I borrowed my friend's code reader, and it came back with PO446, saying Change over valve was stuck closed. The reader said it was a pending error code, and that the issue was intermittently coming and going.
This happened while on the highway at about 70 MPH, and I had about 1/8 of a tank. No noticeable changes in performance, no noises, and the car still runs perfectly. Just wondering if I should just see if it goes away or if I should take it and a few hundred dollars to the dealership...
Has this been a common issue with the 2004 3 2.0? If it helps, just rolled past 113k miles...
