Occasionaly, just after startup there is a obvious noise which sounds
almost like a turbo spinning up. I am pretty sure it the secondary air pump
coming on as it happens briefly right after start up on cold days. Odd that it
only is noisey when it is fairly cold out. No codes throwing yet. Anyway,
has anyone else noticed this.. if so did it lead to the airpump failing.. or???

Thanks!
