I just got my 06 GT Vert about 2 weeks ago and have put 290 miles on it. When the car is running cold, it seems to "backfire" when I rev up the engine. Kinda sounds like a gun going off or "popping" from the exhaust. This happens only when it's running cold and at lower RPM's and tends to go away after warming up. Anyone else experience something like this? Is it something that is happening because the engine's not broken in? The problem isn't too bad, just hope it eventually goes away.

Since you have one in the issues section, I am going to close this one

My suggestion is to take the car to the dealer
