I've got a weird whining noise coming from somewhere inside the engine when I'm driving slowly around in parking lots (1st, 2nd gear, and reverse). Doesn't sound like a squeaky loose belt. As I accelerate, the whining noise gets higher pitched and seems to go away. I don't know because my Apexi N1 then gets louder and it's tough to hear. At idle, there is no noise at all. What could this be?
I only have an Injen intake, Apexi N1, Apexi downpipe.
