Hello,

My check engine light came on today and I went to AutoZone and I got the following reading: PO411/secondary air inj sys incorrect flow. I was just wondering if anyone knew what this is. I noticed that my car has been driving a little bit rough and that it idles a little bit worse. Basically, it feels like the transmission is missing or hesitating. Would this cause it? And also the INSP indicator came on at the same time. Please let me know if you know what the problem is and also the cost. THANKS EVERYONE!

 

I know that the INSP indicator comes on normally after certain mileage, that can easily turned off. As for the timing that it happened at the same time... That's a different story.[&:]
