I have encountered a Check Engine Light and ran the code. It said "PO411" Secondary Air Injection System Incorrect Flow Detected. I looked at the engine and found a bad vacuum hose on the PCV valve, and replaced that, but don't know what this message refers to. Anyone know anything to help me out? Also have a rattle in the rear, sounds like upper shock mounts, but these are brand new. Spare is tight. Any ideas?
Thanks,
