I know it has to do with the secondary AIR injection system and, I searched but no one had a fix for it. I was wondering if this is the little box where the stock air box was, and what the fix was to this problem, also if this would cause a misfire.
EDIT: I have a misfire kinda like a bucking after I first hit boost after that I can not Push WOT with out it bucking and missing.
 
How exactly do you fix this problem? my 95 eclipse rs have the same situation PO412 Secondary air injection valve A malnfunction how do i fix this? not even the computer will erase the Check engine light i feel a tad bit miss fire as well
 
Here is breakdown of how to test it.
