			P0491 and P0492, secondary air system bank 1, secondary air system bank 2 :troll:
 The electric air pump runs with a durametric
 
 The car runs great

 The engine was recently rebuilt from the crank out and the passages to the exhaust manifold were completely cleaned
 
 Any idea how to troubleshoot the system or which part or condition might be the likely culprit?
