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.

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
