ive posted something about this in the v6 lounge but thought id try it here in the tech threads.... i have a 01 5 speed mustang and when ever i get into 3rd ' get to 3k rpm's there's a wierd rubbing/screetching noise that starts all of a sudden. It only does that when i step on the gas too , when i let off it dies down and then its back when i accelerate. I have a CAI and duals but dont think it has anything to do with that so if anyone could give me some info it'd be great . thanks
