Possibles causes for an intermittent P0411 code (?)
I have a P0411 (the flow from the secondary air injection system is out-of-specification) coming in and out. I begun to think that it isn't the pump the cause because I hear it working... I did many light maintenance works on it but I did less on "deeper" maintenance (but the cams are welded)...- GEN 3 SHO FAN
