Hey Guys,

Would codes P0411 (secondary air injection sys incorrect flow) and P0455 (EVAP - emission control sys leak (large)), have anything todo with a lost gas cap.

I've been driving around without for about two weeks, should have one back on later today, but car generated the above two codes within this last week.

Let me know your thoughts please

yes. the gas cap is critical. Get a replacement and the CEL will go away.

i see how it can throw the 455 but not the 411... can you justify your answer?

when i was a teenager this dude had a rag hanging out of the gas-hole on his yugo; we chased him from stoplight to stoplight holding lightings out the window of our car;
