Codes PO 491 and PO 492 Secondary Air system
I've had the Check engine light on for the last 3-4 days and recently got the codes scanned at Schucks that say
PO491 Secondary Air Injection System Insuffiecient Flow (Bank 1)
PO492 Secondary Air Injection System Insufficient Flow (Bank 2)
I need help on trying to fix the problem myself before paying for a real mechanic. Any suggestions?
The car runs fine! Its a 2001 325xi wagon with about 34,000 miles.
