I replaced the catalytic converter about 3 months ago. When I accelerate quickly the malfunction indicator light that is on starts flashing. The car hesitates but once I let up on the accelerator & keep an even speed it stops blinking is just lit up. My manual says a blinking indicator light is an emission issue with my catalytic converter but the 413 code says secondary air pump open circuit.

it could also be misfires.
We replaced the spark plugs which helped a little, but I did not replace the coils. They have been replaced before probably 3 yrs ago?? Any advice on how to go about figuring this out would be greatly appreciated! Thanks! Debi
