After the work was done, the check engine light was gone, but it's now come back, 525 miles later. As a result, I can't pass the functional part of the California smog test. The smog guy's obd2 scanner identifies the problem as incorrect purge flow.
I think there might be many causes of this scan and wonder how to go about chasing down the source of the problem. I have replaced the gas cap.
have the same problem?
