Ok, I know my IAC valve is bad, I just wanna know if this will cause a problem if I let it go for a lil while longer. I cant get it fixed anytime soon, but its only causing problems when the temperature is at or below freezing (32 degrees F). Basically my idle acts really weird (idles high then almost kills itself) and I got a VERY LOUD hum (caused from resonation up the air intake). Right now its just a pain letting the car warm up in the mornings, hoping that it doesnt die. Is this going to cause any damage to anything else?
