I get this fault, seems like after its been idling. I get the fault second time now in 1 week. I have cleared them via the scanner. I drove the vehicle home for 1100 miles after I bought it and the code didnt show up for two days after I got it here. Could this be related to a pcv valve? I really need help with this one I dont have a manual yet, could anybody provide a workflow for this? Thanks-

 

Secondary air pumps just help "pre heat" the cats for better emmisions.

They are the two pumps on the back of the motor you see here. Check the plugs and hoses going to them. If they are all good you probably need a new one. Not sure which one is "bank two".
