did some rountine checking and found that the small hose connected to the flame trap is rotted and totally shot (larger one seems fine). Where do these hoses go? i can feel them under the manifold but can't reach my hand any further, i didn't see anything on bay 13 (or was i not looking hard enough?). I know there is a code for "secondary air injection" coming up when i got my ob2 scanned(told it was air pump) could this hose be the problem? (car runs great but gets poor milage). To replace these hoses what am i looking at removal of injectors/manifold?
