i own a 2010 Mustang GT with 8,200 miles on it. Since Ive bought it, I have added JLT CAI, Bama tune, Flowmaster axel back and 3:73 gears.
Ive noticed recently that when the tach gets to just above 4,000 RPM's i hear knocking coming from the engine. Almost like a fast ticking sound.
Assume I am the biggest mechanical moron you have ever spoken with and fill me in on possible reasons why this would occur.
