Approx., 4 months ago I got my car out the the shop for the cleaning of my heads which cost me about $8000. My SES light is on for secondary air flow pump which I've been told it doesn't affect driviblity. Should I pay to get the pump fixed or continue driving it as is? I've been told to do the pump it will cost $1500. Since the heads were already cleaned do anyone know if I have the pump fixed will it give me that blue smoke that everyone says will happen with this problem?
