I have a 05 6M GTO with less than 600 miles on it. It has developed a very loud and annoying “ticking” noise. It happens in any gear (louder in the lower gears) and is most noticeable when approaching a stoplight. Example being, cruising say at 45mph and coming up on a red stoplight, let off the gas and allow the car to slow on its own… once past the point where the exhaust quiets down a bit you here this loud ticking coming from somewhere under the car. The ticking stops when either the clutch or the accelerator is depressed. I did try the search engine here at the site but didn’t come up with anything. Any thoughts or ideas as to what the cause could be would be greatly appreciated! Thanks...
