whining when starting
Good Day!
I sent my car in for a cat replacement, which they did, now when I start it it whines really loud! There is an electric motor running that is super loud (sounds like a turbo spooling or something). The motor is located near the passenger side strut tower. It runs for like 10 or 20 seconds and then shuts off. This just started after they replaced the cat.
Anybody know what it is? Is it a problem, or is the car supposed to do this? It never did it before (I've had the car for 1.5 years).
Thanks!
Rob

its called the secondary air injection pump.... its used to heat up the cat faster with cold starts.... its a tiny electric motor that spins two thin metal "fans." My cat failed on me aswell so i gutted it and now i am running an "oem midpipe." The whine also happens with me so i took the sucker apart and oiled it and made sure everything was balanced.... did nothing... still whines.... i would say do not worry about it........ just every now and then check to make sure the unit is not producing any smoke or is getting hot as that would mean the metal fans are rubbing against the plastic molding....
