I have the 2005 Mustang V6(stock). I was wondering if others are getting any weird sound from the car when they are on the throttle an little bit when accelerating? I am getting it all the time. If so, Please help.....I don't know what to fix or replace..

 

See if this sounds like what you're experiencing:

I heard the 6's make a screaming sound when you run'em hard.

 

LOL> Have you ever owned a V-6 Mustang? Because if you have you would know this is normal. The V-6's they put in the Mustangs are way too noisy. Just the engine.
